Well, speaking as a regular/heavy user of Twitter (yes, it's gay as hell, but when you're a blogger, it's an almost essential means of getting your name/nonsense out there), I was initially going to applaud Google's efforts, which is about a billion times more useful than Wave.
And then I stumbled across the comments section of this post and check out all the complaints...

So yeah, once again, Google took what should have been so simple and made it needlessly complicated, like always. Congrats.
