Maybe I'm just jaded but all these things just seems like tired old rehashes of the same ideas dressed up with new names to try and make them sound cool.
If you send me an email, I will get a notification popup because my email notifier does it. If you send me an instant message notification I will also get a small notification popup because I am running an IM client. If there is a way Yip works better than those then I'm struggling to think of it. I really don't need more ways to receive small notification popups. We have XMPP, we have SMTP. Stop reinventing wheels.
