I would almost be okay with a proffer that it is bots asking the questions, but that the discourse is between human beings. That's all I really care about. It's rare that I respond directly to OP, or at least I do so less frequently than I'm responding to someone in the comments.
I remember back in the early days on forums, sometimes they'd just feel dead, and it was mainly a lack of content (threads). Once a thread would open, us morons behind keyboards could talk it to death, or more likely just divert in perpetuity.
That's a really good use for bots, since new users haven't seen the best posts and may actually enjoy discussing them. Older users can simply move on, filter from their stream if they get bored of it.
