It has been almost two weeks since Google Wave was announced, so I thought I’d write a little about my thoughts on the subject. I have actually waited with this blog post because I haven’t been exactly sure what I think about it yet. Of course, I’m still not - but hopefully I will be able to get some of my thoughts collected by writing this post.

So let me start with the basics. Google Wave is a combination of email, instant messaging, forums, document creation and much more. The core concept is the wave, which in turn is comprised of blips. The blips are what actually contains content. Blips are threaded in terms of each other. The most different thing about Wave is probably that a wave is persistent and centralized. The model assumes that there is only one instance of each wave (although they can be federated and cached temporarily).
