Because they’re typically steeped in subjectivity, product reviews tend to be more effective when grouped together. This is generally why you, the consumer, often want to consult with multiple sources and individual perspectives in order to make an informed decision before you proceed to checkout. So, just to make things a little easier for you, we’ve put together a brief list of places on the Web you might like to go to stock up on opinions about a myriad of products, from gadgets to vehicles to attire to the miscellaneous, before laying down your hard earned cash.

Perhaps the most abundant catalogue of product reviews on the Internet, Epinions, a Shopping.com property, is a megaplex of pretty much everything under the sun that pertains to human lifestyles of all sorts. Indeed, its supply of notes about electronics is vast, but it is also holds its fair share of opinions on travel, restaurants, and food and drink. Suffice it to say that its variety is as much a strength as is the sheer volume of information it manages today.

A bit more rough-cut, but supported by Web-based heavyweights (About.com, NYTCo), ConsumerSearch is touted as a reviewer of reviews. While not the prettiest player in the market, the quantity of information found on its servers is quite large. If you’re willing to forgive its bland interface, you might find it a resource worth visiting and revisiting once in a while.

This one’s an oldie for sure, but still relevant. Some might pass it off as a review source too focused on detailed research and less about connecting consumers with the broadest product list possible, but ConsumerReports has been trusted by a large number of readers for many years, and continues to play a very active role in the field. If nothing else, it’s one more place to go to achieve that well-rounded view you’re seeking.

Amazon is a retail giant, for sure, but its product reviews are a massive resource in and of themselves. Some items will show pages of feedback, while others will show less, or maybe none at all. But taken as a whole, Amazon is a destination as valuable for its convenient shopping mechanisms as for its consumer commentary.

If electronics are your focus, CNET carries some merit among review sites. The in-house review staff at CNET regularly put out text and video reviews of gadgets built for business and personal use, and user input helps to complete the picture. CNET was purchased by CBS not too long ago, and some are expecting the adoptive parent to focus more on the TV-style projects being produced at the technology site, but for the time being, CNET is still a decent choice for aggregate opinion.

We covered Sazze earlier this year when it introduced itself as product review site with a social component, and it continues to look like a solid place for reviews. Its home page highlights a select number of products, and beneath the cover there are thousands more. There’s a good chance you’ll find what you’re looking for here, and each page is laid out intelligently, so it’s all very easy to browse.

Reevoo launched last summer, and in that time it has built itself a bit of an international name with the debut of a French adjunct in March of this year. Simple enough to use, with a database fronted by five main categories - ‘Phones & Computing,’ ‘Entertainment,’ ‘Photography,’ ‘Home & DIY,’ and ‘Toys & Baby’ - Reevoo has quite a lot of reviews and ratings beneath the hood. Take a look, we say. You might like it.

Not to be confused with the option above, Retrevo is sort of a hybrid of reviews and general product information (product manuals, etc.). The site is completely intuitive, and while its presentation of data might not be everyone’s favorite cup of tea, its gets the job done.

You might like it for its name alone, Buzzillions, but past the title, it’s actually a good piece of kit. It has a wide reach across the product realm, and everything is pleasantly wrapped. It is for sure one of the better places to visit among sites listed here.

Another product search and review engine that presents itself as infused with expertise, Crowdstorm is low on material on its front page, which might be a touch disappointing for some visitors, but its method of delivering information is rather interesting. You can browse for products manually, or ask for “expert” advice on stuff you seek to buy. Crowdstorm operates sites for both US- and UK-based audiences.

PEbuzz is one part social network and one part gadget review joint. We offered a few thoughts on the site some weeks back, and while it could definitely use a nicer, more modern exterior, it may well be what you’re after. For what it’s worth, PEbuzz is free to join.

Photo enthusiast are you? Look no further than Digital Photography Review. Covering everything from the latest industry news to detailed - and we mean detailed - product reviews and comparisons, DPR is the place you want to go for anything to do with digital imagery.

RateItAll has some decent offerings. It likes to tout lists having to do with anything deemed culturally or consumeristically (not part of the official lexicon, but we’ll go with it all the same) significant by the populace. Will this serve you well? That depends. If you’ve read this far, it’s safe to assume you’re privy to lists. And RateItAll is right down that alley. The site also offers applications for Facebook and MySpace users.

Omgili covers more than just product reviews. Or, as it describes them, “consumer experiences.” But part of the puzzle has to do with stuff you buy, so what they hey, it gets the final spot here. Enter a search term, and you’ll get back a search page with product results along with ratings bars that manage five degrees of buyer approval/disapproval, from “excellent” to “miserable.” Omgili pulls reviews from about seven independent sources, including Amazon, PriceGrabber, NewEgg, CNET, Target, Yahoo Shopping, and Edmunds.

This is a guest post written by Chris Brogan, who blogs about social media for business at chrisbrogan.com.

There are only so many hours in a day, and you’ve got to determine which social media tools drive business, which ones build community, and where you can learn the most in the process. Maybe you’ve built a blog or a home page or some other starting point for your online presence. How do you manage the rest of your online presence, and how do you keep track of everything? I have some ideas for you. Let’s start by building the following:

Listening Post

Get a Google account and get Google Reader. Go to Technorati and Google Blogsearch. Find the search bar and put in:

-Your name in quotes.

-Your company name (if that matters).

-Your competition’s name.

-keywords to your industry.

Every time you do a search, look for the orange RSS subscription button on Technorati, and click it. Look for the RSS subscription link to the left on Google Blogsearch. Click it. Add all of these to your Google Reader (upper left area of the left sidebar).

You’ve just built a rudimentary listening post.

A Social Hub or Two

Go to FriendFeed. Build an account and add your blog, your Flickr photos, your Upcoming.org, and your whatever-you’re-doing-on-the-Web into it. This is another way to share out what you’re doing, but also another place where conversations are happening that you might not see if you’re not there with another kind of listening post.

You might also check out Lijit, a service that offers a different spin on a similar thing.

Some Social Network Outposts

At this point, my top 3 choices for social networks are:

-LinkedIn - for professional networking.

-Facebook - for social circles.

-Twitter - for everyday conversation and networking.

I belong to and use several other networks for different things, including Utterz (I’m on their advisory board), Flickr, several Ning sites, and a few other niche things. The three listed above are the ones I think have the most resonance. You might substitute MySpace for Facebook. You might like Jaiku more than Twitter. The details don’t matter. I just listed what I feel are the best choices at present.

On those sites, amongst other things, be sure to point links back to your primary site or your blog. Thread the needle for people.

Note: several of these sites also have RSS subscriptions for comments and other updates. You can add those to your Google Reader, too, to keep track of it all.

What to Do With It All

This is partially difficult to answer, as it’s up to you what your goals are for using social media. But some of the things you can do once you have this all in place are:

-Learn who’s talking about you (or your company, or the other keywords you put into your reader), and engage them in conversation on their site.

-Make relationships with others before you need them on social networks.

-Find other professionals in your field, or in unrelated fields on social networks.

-Connect with old friends and business colleagues.

-Discover new people through reading and learning, and follow the media they make on the various networks, and/or in Friendfeed.

-Learn more about your competitors through the media they make, and discover where you can build more value.

Obviously, there are dozens more possibilities. If nothing, I hope to have provided a potential starter kit for managing some of the elements of online presence around your primary blog or website. You might have some different experiences along the way, and some parts might not work, so feel free to adjust. Your mileage may vary.

Would you add anything else to this premise?

We’ve learned that the Swiss version of Technorati has put itself up for sale this week. The site is called SLUG and indexes about 2,200 Swiss blogs. Currently SLUG shows 460,000 posts in the index which are categorized by topic.

The current "seller expectation" on the auction is 25,000 Euros or $40,000 USD. If you are interested in the auction, it’s being held on Sedo.

The site features a very interesting geo-location map which shows bloggers by location. Click a blogger and see his or her latest posts.

PE Hub reported today that Technorati just got another round of investment - this time it’s a $7.5 million on a Series D. Now they have about $30 million from investors including: Draper Fisher Jurvetson, Mobius Venture Capital, and FG Incubation.

Technorati continues to disappoint me with their inaccurate blog scoring and their poor blog search. I still believe half of their servers are not updating properly. Sometimes when you visit a blog’s stats page, you get nothing, sometimes you get a higher score than "normal" and other times you get half of the page.  

Dan Frommer reports that after the announcement the Technorati service went down from massive traffic. He believes that many people went to the site after many years of ignoring it, assuming it was dead.

CEO Richard Jalichandra seems to do a good job of hitting the party and event circuit so perhaps that helped the company to receive the funding. Last year I wrote a column at BlogWorld about Jalichandra where I said he "blew it." Though on the positive side, he did try to friend me on LinkedIn last month. Last year, I even offered the company five suggestions to immediately improve Technorati.

Perhaps Technorati and Alexa should merge?
