Stowe Boyd was ruminating earlier this week about the need for a Web site to take a hard look at some Web 2.0 services six months after they have been profiled by TechCrunch. It turns out he inspired two German entrepreneurs who are poised to unveil a site this week called Techcrush. Not sure if Techcrush is a spoof but some retrospection on the Web 2.0 landscape would be interesting. A good example of a Web 2.0 service that deserved to be re-visted is Flock, which was drilled when it released an alpha version of its browser last year. While Flock's developers likely had good intentions, the browser was far from cooked and looked bad in comparison with the alternative browser du jour, Firefox. Several months later, Flock released a new and improved beta that was a huge improvement over the alpha. Of course, Flock's beta didn't get as much attention because people had already moved on to the next new and shiny thing. I'm sure there are lots of Web 2.0 services that need a second chance in the spotlight after getting off to a rough start; just as there are many services that received lots of buzz and hype only to come back to earth. Update: Speaking of Web 2.0 services, a new version of Go2Web20 has been released. It's pretty.
