Damn it I love Google. This here is a lovely little story on the GoogleTalk talkabout (their blog).
What do you mean you've never heard of GoogleTalk? You mean you still think msn Messenger is a good idea?
GoogleTalk is Google's own IM and quality Voice Over IP software. Sure it doesn't have all the features of Messenger (thankfully) and you sadly can't set up conference calls (yet...). But it's Google. It works. It's beautiful. And it now has the feature to add a personal icon (some of which are pretty cute).
Go get it now and then get me on your list.
