Captian Kirk himself, William Shatner, recently joined Reddit to participate in an AMA ("ask me anything") for Star Trek fans. To redditors' delight, he's stuck around the site, getting the hang of things and interacting more with Trekkies.

On Friday, in a message thread for admins about suggestions for improvements to the private messaging, Shatner says he's been "appalled" by some of what he's seen on Reddit, and questions why it isn't moderated more.
