Startups That Came Back From The Dead

I'm not sure one can possibly say that a site that's only been around for a few months (like FriendFeed) ever experienced "death". I'm sure Paul would be surprised to hear it.

And, many of the ones that I might agree look a little moribund (like Mahalo, perhaps) also haven't really proven that they have a real life ahead of them.

It's just too early to say much about most of these startups, and I'm not sure there's a lot to learn from trying to analyze snippets of Alexa data to indicate their life/death status.
