I really would like Google+ replace Twitter. Lately I've found Twitter quite stale. The web interface is slow and clunky (yes, the new new one). It's just too big for them to make big ui changes.
I'd love to see Google+ become the new, eh, social network to be on. That's obviously what Search+ is all about.
It's somewhat like Apple getting rid of the floppy disk, and more recently Flash, it's a bit painful, but it's a good thing in the end. Out with the old, in with the new.
