Hi, rest assured, it isn't bogus. The amazon servers are a little spotty sometimes so all we can recommend is to keep trying and it will connect.
We released a new version (1.1.0) today which introduces interests and an easy link to your PinShare messages inbox for OS6 and later. Some of the users were having a little trouble figuring out how to open their PinShare messages, so hopefully this should increase the likelihood of getting a response. Of course you have to understand that everyone might not want to be friends with you, so don't get discouraged if you don't get a BBM invitation from them, there are lots of other people using the app
