I suspect that Google Wave is going public really soon now. I signed up for Wave a couple of months ago but got an invitation via Alfons. Just a couple of hours ago, I received my official invitation. How about getting two invitations within 2 days?
My initial thoughts are mixed: Like other social media forms, Wave would work perfectly if you have hundreds of friends and relatives and participants. This doesn’t mean that it doesn’t have its usage. I guess, you could use it as a personal notes keeper for your sources.
When I have time, I’ll have to take a closer look at this.
