"Bots Are People Too" :) Thanks for your input. It helps clarify some of my own thoughts.

I was thinking, if it's about being social, and the bot is capable of being social (like Watson) wouldn't THAT be a wonderful social experiment?

I agree that bots who only go through and up-vote peoples posts, regardless of quality are a bad idea. I would think the moderators of the site wouldn't want that at all. If it creates a valid discussion, though, that sounds great to me.
