I'm sure you can appreciate that I have to respect the confidentiality with which I've been entrusted as a Google employee. This includes not only commenting on internal matters I do know about but also matters which it may appear I have knowledge of. It's not in my interest or Google's for me to unwittingly start a rumour because of something I carelessly say.

Wave predates me joining Google. My thoughts on it predate Google (I think I wrote a blog post about it some time last year).

So, just to be clear, any views expressed here are strictly my own. I'm sure you understand.
