That might be the most obnoxious design for a blog I've ever seen. I'm not quite sure what their point is. Google Wave is intended to be a reinvention of the user interface we use to communicate, and I think it introduces features that make a lot of sense:

- Sending all user a thumbnail while the full image is still uploading - Instantaneous character-by-character update in chat - Better management of conversations

They're all things that would make for a really nice experience. There are things about the protocol that don't make sense to me, but that hardly reflects on the quality of the product. I would've chosen a more compact format, but then it wouldn't be as customizable. They're designing it more for the user than the developer.

edit: Their other posts are more revealing: http://pwpwp.blogspot.com/2009/08/wave.html

Whoa, the fonts on that blog make my head asplode.
