Uncov has a very funny post on the demise of Kevin-Rose-founded-Twitter-clone Pownce, noting that their traffic seems to have fallen to the point that “Even TechCrunch can’t save you now.” The image above is taken from their post.

That may or may not be true, but when you look at Pownce v. Twitter on Compete.com, the difference doesn’t look quite so brutal. Still, there is probably only room for one Twitter in this world, and Twitter itself seems determined to hang in there.

Pownce, previously a one-person shop (developer Leah Culver), has started to hire people and is looking for office space. We’ve also heard Culver doesn’t like Pownce being called a Twitter-clone. But the shoe fits quite nicely in this case, and the clone moniker stands. Sure, there are differences. But it isn’t different enough.
