Reviews for startups have always been extremely artificial. In an ideal world, users would be very vocal about what they like and don't like. Surprise, they're usually NOT!

Techcrunch in particular is a traditional publicity channel that gets most of its information through heavily biased sources such as press releases, friends, etc. instead of directly from the users. This is why I find it hilarious that techcrunch should be the ones to call them out on producing biased information.

Then again, Arrington has been working to discover sites as a user through hn for example, so he may be doing a small part to correct this wrong.
