I don't know if you guys have heard of reddit. It is a forums based site, with many subforums for basically any subject. One of the subforums is AMA, which stands for Ask Me Anything. It is basically a Q&A subforum where famous people or just interesting people host a Q&A session. This friday (the 24, at 3PM eastern, Alton Brown is hosting an AMA (Q&A) on reddit.com.
I thought some of you guys might be interested in this.
