I am Jeph Jacques, author of Questionable Content and professional internet cartoonist. AMA
I've been doing Questionable Content full-time since 2004. I'll answer questions for a couple hours or until I decide not to answer questions anymore.
Edit: Okay, I think I'm done. Thanks for the questions you guys, this was a lot of fun. :)
