I like that it is easy to use, but you can't put in any personal information unless your friends invite them into an app circle! There are so many options of apps/circles available now - why do we have to limit ourselves? Also, since there's no option where users don't see what other people said (just 'liked' or didn't), how can one know if others dislike something posted without reading all comments first?! And also, it would be nice to show who has liked which post. If someone were looking at my profile page, i think this feature could help me make better decisions when deciding whether to follow certain pages / posts etc.
