Am I the only one who prefers regular gchat to google hangouts? It's super difficult to figure out who on my contact list is online or not. I also mistake old msgs as new ones because of the lack of time-stamps. Maybe I'm missing a check-box or something that could fix all this but I gave up and switched back to gchat almost immediately.
The real shame is that Google already had a fantastic offering and they killed something beautiful: an integrated product that included a real time communication client (gchat), a messaging service (gmail), and a group/community based social network (g+).
