Lots has been said about the new Posterous Spaces. Here's my thoughts:
It sucks.
Hate the new interface. Hate the social aspect (who needs another network?). Hate the fact that I can't do a simple thing like post pictures like I used to be able to. I've tried four times to post a picture and the app just hangs (iPhone).
Change us good.
Screwing up something that worked is bad.
