I was about to use it as a OS-independent alternative to Skype (I'm on Linux). And I wanted to use this, also instead of facebook chat and the likes.<p>The moment they removed the contacts feature it was dead for me. Although, to be honest, it never really worked (sometimes no audio and stuff like that).<p>The idea, that I have to first email the chat URL and then I can make a conversation is like writing a letter first before doing a call. Fundamentally wrong conversation setup.
