I made a status update on Facebook about how every other e-mail I got lately at work was about something that was supposed to be not public. I hate keeping secrets about stuff like that, though I've been bound by that stuff for years since I had access to pre-release stuff when I wrote my book. And honestly, part of it is my own doing, since I'm participating in two big deal beta programs (neither of which has anything to do with the phone, by the way).
Fortunately, we do have some stuff that's pretty out in the open. The ASP.NET MVC team is practically an open book on virtually everything short of hopeful ship dates. Their PM, Phil Haack, blogs pretty regularly and they put out preview versions of stuff. I love that. Even the Windows Phone 7 tools came out as an early preview, something like six months before the thing will even come out.
Still, I don't like secrets!
