It may be "something wrong" for you, but for me it's exactly what I need to let my mother video chat with her grandson after Skype became useless (breaks more often with every passing release, it seems; we've given up on it).

Sharing links, accounts, chat, logging and persistence are all irrelevant for my use, and they in any case don't belong in webrtc - webrtc is a component for people to use to build services like what you appear to want.
