Skype - get it and shutup.
wow so when did they add B.net skpye ALERT THE MEDIA----Blizzard and Skype are partnered.
so this still doesn't solve the problem
i use Skype as well
"Hey, do you have skype? Nice, what's your email/username?"
"Hey, do you have skype? No? go to skype.com and spend 4 minutes downloading, installing, and creating an account!"
The problem, it is solved. Skype is an awesome voice-chat system as well as an awesome IM system. You can search for individuals through name or email address among other things. It's so easy to use, and so easy to add others through. Just sayin'.
Quit being a scrub-tub and use Skype. It's already the preferred chat/voice chat system amongst gamers, we really don't need more Blizzard shenanigans, especially not a third party program imo.
Wub : COME AT ME BRO! If your friends don't use the same system as you, you just have to elbow drop their mouths and force them to use yours. It's so easy!
Edit : I just read over my post, and I think SKype should be paying me for this. :P
TLDR - There are already great programs out there with perfect functionality and ease-of-use. You can chat in any modern Blizz game across games (WoW, SC2, and soon to be D3). The OP has a poopy butt.
