I like how it gets instant push notification if I get a notification, that's really cool
HOWEVER opening a post from the notification clears my app history completely, and so does clicking the icon in the launcher, and I find that to be rather counterproductive
Also it's really hard to read the original question when you're answering comments on your opinion, and it's hard to look at the original question while you're answering that question (it opens in a new activity that comes in from the side), and that makes it rather difficult to use. :/
It's good, but it also means I'm never disconnected from GaG, so when you're trying to do homework and your phone is on, it's a pain. I'm waiting for the Takes and messages features to be added on though, because that's where I invest the majority of my time spent on this site.
