It’s gearing up. After a quick burst of hype, culminating in its official Web 2.0 coming out, the critics are lining up to take shots at the new Firefox-based “social browser” by Palo Alto start-up Flock (which we profiled here.) In a post titled “Flock Never Stood A Chance,” Scrivs over at Whitespace is already calling game-over for the still-in-beta Flock, asserting that it’s trying to solve a non-existent problem.

“Flock never stood a chance in replacing Firefox as the default browswer of the non-IE crowd or even have a chance of penetrating any markets,” he said “I know it’s still early in the life of Flock, but where’s all the positive buzz now that it’s available to download?”

Flock founder Bart Decrem jumped to the product’s defense in the comments section: “We believe that the web has evolved, the browser experience hasn’t, and there’s therefore a ton of room for innovation. In particular, we believe that there’s a ton of work to do in building a web browser that integrates the social and two-way aspects of the web. We believe that there *is* a big problem to be solved: talking back to the web (blogging, even sharing pictures) is a royal pain, and the browser has not lived up to the original vision of Tim Berners Lee in this regards.”

Flock’s Chris Messina and Scrivs pick up the debate here.
