I am watching the video preview of Google Wave, which is the hot topic that was demonstrated yesterday at the keynote of Day 2 of Google I/O.
Interesting stuff, open source, and the preview is a means for people to start thinking about apps they might write to enhance the use of this product, before it becomes publicly available.
The multi-faceted communication possibilities are very exciting.
I watch the video, it is quite a product. It is like many things all in one. I can see it will change networking again, and email between regular users will change. I always wanted something like this for my team. It give creation to a lot of possibilities.
