What do you want Teamspeak for?

Sure, this idea is not new but some people seem not to know about it. What is the idea? To use Steam for all your voice chatting purposes.

Really, what do we need Teamspeak for? Steam groups are free, you can create as many as you want and you can setup your VoIP properties all to your wish. Besides, Steam voice chat is as good as Skype which is popular for a good reason.

All I want with this group is a) spread the word and b) have a group chat for my own VoIP purposes.
