Don't be dumb like me and be sure to hit Stack Overflow with your phone or laptop sometime during the day so you don't reset your "fanatic" timer.
I'm fully expecting to be posting answers during DevDays... at least occasionally.
I promise not to do so during my own talk though.
(I should try to remember how the outside world tends to treat presentations, actually. During Google Tech Talks it's entirely expected for a large proportion of the room to have a laptop open, checking mail, doing code reviews, etc. while people are talking. That doesn't tend to go down so well elsewhere.)
Ok, I promise I won't be as dumb as you.
