This seems to have some issues. I tried many different connections and none worked! I tried a direct connection as well. Apart from that, I suggest including a "text message" in the search bar to inform users what they can enter. I had a question - "Instead of entering a username, can I enter "Sales at Amazon" and will your system get my connections at Amazon?" - didn't know where to look for. Also a small change - Move logout link to top with FAQ, About as the linkedin alert masks it. Finally, consider providing cross connection through linkedin and facebook. That would be useful. Otherwise this would just be another implementation of Facebook connect.
