I’ve been a preview member of Google Wave for a couple of months now. While I still don’t know a heck of a lot about it, I have found that reading what other people are doing with it has helped to keep it on my radar. Will it replace email? I don’t know, right now I’m leaning towards doubtful.

Gina @ Smarterware posted a great FAQ about Google Wave and it answers a bunch of question I had and gives you a better overview of what Google Wave is and how you can use it.
