Well the answer is clearly no, I have absolutely zero need for an invite to GoogleWave at all.
That said I would like one, just to see what all the fuss is about.
Once it’s been released, and there are lots of people using the service I’m sure it will be awesome. At this stage though I reckon it’ll be pretty limited for the people that are in the beta (oh wait, it’s not supposed to be referred to as a beta is it). Unless you’re in a community which uses Wave, it’s really not going to be of much use as far as I can see.
I think the idea is fucking awesome though, and can’t wait to see it once it’s being used as it should be
