It's a challenge for any site that focuses on the Scobles of the world as their early users. What happens when it they want to change the vibe to make it more broadly appealing?
It's certainly not fatal. Twitter navigated through it a couple of years ago, when a lot of the old-timers (including Scoble) talked about how it had lost its appeal and FriendFeed was the wave of the future. It'll be interesting to see what Quora does.
EDIT: although I do think Robert's right: Quora isn't a very good platform for blogging.
