Twitter is empty, and all the tweets are here?

I know that it's against the guidelines to complain about HN becoming reddit - this is not that.

I am curious if we can expect a mass migration of twitter users disrupting the cultures of other sites (even possibly this one)? Mods might have their work cut out for them even moreso than usual.

Any predictions on what this does to the overall internet comment landscape? Assuming many users actually do leave twitter that is.
