I find this approach really exciting. The fact that it builds into existing communication channels is very very cool, and the idea of a scalable real-time service is powerful especially for mobile. I like the idea of more services embedding directly into my core communication -- chat, phone, email.

I've been a beta user of this since the middle of 2008. It's a great service.

(I have invites if they're still not open. Use the contact info in my profile if you want one.)

Hmmm... This is also the name of a (fairly old) regional search engine - www.aardvark.co.za.

Looks nice.

ChaCha tried something like this and failed before converting to their SMS service.
