I don't think its about a leak.  I think that people who are used to being able to talk about things with their friends/acquaintances are starting to run into a wall they have never encountered before.  As they are being told, "I've got nothing" or "I can't comment on that", they are starting to see that something is up.  As to what, that is something you'll have to get from another avenue.  There are 3 streams of info right now.  2 streams from the different boosters, and the AD stream.  AD stream is mum (at the right level), and the two booster versions I've heard couldn't be anymore different.  I was listening to one, until starting to see AtlVol/Beaver's accounts.  While I may still have some reservations, I have at least heard some things first hand that would corroborate.  I think what happens with this hire will recalibrate some insider sources.  People who have trusted sources, will have to see that information may be flowing out of different faucets now.
