Cool. I reckon he should definately interact with C9 more, I know he's probably busy but in the 11 months I've been here, I've not seen a single post by him, so...
That would be funny, just imagine the reaction that you'd get if BillG actually posted unanonymously, (non-anonymously?).
It'd be slashdot central in about 30 seconds, with hundreds of posts about obscure things the NSA is supposed to have added into windows.
Hehe... still, it'd be interesting. Maybe an interview and another "What do you want to know about Vista" style thread but what do you want to know about MS in general?
