> Am I the only one who is a bit disappointed with the slow speed of development of G+?

Yes, definitely. When it came out I was blow away by the utility of the Android app which pushed my photos up to the cloud into an online gallery where I could instantly show them and share them. There were a whole lot of rough edges but I was sure they would get dealt with in short order - the functionality I was seeing was a break through, a killer app for me. But several months later, ALL those rough edges are still there. The G+ app still is not optimised for tablet in any meaningful way. There is no way to have have a hang out using your phone or tablet which is a huge use case. It just seems to be crawling along, presumably they are busy doing stuff but it doesn't seem to be focused on rapidly improving the user experience the way I was hoping.
