Update – August 2010 – Google announced that they will stop development on wave due to low adoption rate.  If you currently use it, it will be available until at least the end of the year.

I’m sure this isn’t new news to many, but Google released their version of web based collaboration software not long ago.  Currently you have to have an invitation to use it (similar to what they did with email when gmail was released).  I finally received an invite and have had a chance to experiment with it.  My first thought is that it will be very cool if you can get people to buy into it.  Personally I use google for email, calendar, document management and other things, so I will no doubt be using Google Wave for collaboration.  Here’s a short video from their “googlewave” channel that explains what it is fairly well:
