"People who only know how to be a persona — who want to tell the 'movie star story' — you won't want to do it," said "Burn Notice" and "Evil Dead" star Bruce Campbell, who held an AMA last year. "If they ask me about my personal life? I say, 'None of your business,' and move on."
Other sites like AnyAsq.com, entirely based on crowd-sourced interviews, haven't really caught on in a big way, and part of the problem is that those most likely to read and participate in AMAs are fairly marketing-resistant. Others, like Redditor Brenden Sherratt, who does social media and online marketing for Sortable.com, worry about success spoiling either the AMA format or Reddit itself.
