Hard to imagine that PG doesn't have sway over what the board decides if he should so desire. Obviously. But he can defer to the board in day to day and use it to his advantage. (Remember Godfather 1 "Michael's in charge now".) So playing the card will be a rare occurrence but possible.
He retired, for some definition of retired. He's letting the new team run the ship. That said, I'm sure he's still virtually on the board of directors and if he really felt passionate about something that it would get done.
He's clearly above this board and could get rid of all of them if he wanted to. I think all involved know and understand that, and hope it never has to happen.
The demo is currently restricted to 4 languages: english, portuguese, spanish and french. We do have chinese editors and can support chinese characters in the live product, but are not offering it right now, as we don't have critical mass.
Thanks for the heads up about the blog. Corrected at the end of the post.
