It's going to take a lot to get people to move because as Leo says, everyone is already on Twitter and you go where your friends are!

that if Twitter gets working again there won't be much of a chance for Plurk

Here's my opinion in 140 words or less snipurl.com/2e4ca well more actually

If twitter manages too get back and stable with IM etc.. Plurk or any other service for that fact Has now chance

stability is the key people are tired of twitter being down. Loosing a user is easy they go to where they fell better Returning them is hard

it's getting up there
