I just received my Google Wave Developer Sandbox account today, and so I’ve spent a good part of the evening playing around with it, finding my bearings in the interface, and working out how it all works. So far it looks like a very nicely integrated communication system, with a lot of API access to ensure it develops rapidly. There’s quite a few bots already running, for code syntax highlighting, for blogging, for starting discussion groups and a whole swath of other things.
Here is a screenshot of a wave:
This wave is a collection of hints and tips on how to get started using Wave, and is a really handy FAQ to get things rolling once you’ve got your account setup.
And here is a shot of the entire interface for Wave, with a wave open that demos some of the stuff that can be embedded into a wave, in this case Google Maps.
As far as browser support goes, I’ve mostly been using it in Chromium (22.214.171.124), where it seems to work best (Surprise Surprise). It didn’t even recognise Firefox 3.5 as being a browser capable of handling Wave for some reason, but 3.0.11 was fine. The experience is a little laggy, but that could just be because it’s only a preview implementation, and therefore is probably not well distributed (like most other Google services usually are).
