A sad thing has occurred. Google has announces that there will be no Google Wave at the end of this year. Having used this for online RPGs, it is a fantastic tool, and I'm very sad to see it go. But I can understand. It was popular for the first couple of months and then it just fizzled out. Even though I admit that Wave is a superior tool for meetings and online collaboration, for some reason it just didn't catch on. Maybe because it wasn't as easy as a chat room. Maybe it'll be more useful to the market at a later date. I can only speculate.
Google Wave, you will be missed in my nerd circles.
