Looks like there's a chance that the infamous JoCo (Jonathan Coulton) might be coming to Vancouver. According to his JoCo in the Future page he lists Vancouver as "Maybe" and "TBA" for more info. Feel free to flood @jonathancoulton with messages of support for a trip to Vancouver.

JoCo, if you don't know, is the mind behind "Still Alive" from the Portal Video game, "Code Monkey", "Re: Your Brains" and many other great comedy geek music hits.
