Google Talk has launched. It’s not like I need another IM protocol to use, but I’m available on that now as well. Only Windoze users can use the VoIP (voice chat) function, but that’s okay. I use Skype without any problems when I need to use it. The only way I see Google Talk being anything special is if they really expand the voice chat capabilities (getting it on other platforms for starters) and make it easy to use.
