I think this a little unfair - if the format seems formulaic and the faces familiar, maybe that's because you're a regular and the message is just still getting out. And besides, what conference series doesn't have the same vibe? Isn't it always the same inner core driving the dialogue? Maybe conferences aren't the right medium for evangelizing Gov 2.0. Personally, as an anonymous federal programmer, I find these conferences a real breath of fresh air - even if their speakers are getting bored... And I think I represent the audience you most need to inspire.
