Probably. I knew about the show from following him on Twitter, but since most of the people there were obviously students I'm sure there was some kind of advertising on campus. Although I don't know how much advance notice even the students had, because floss himself didn't seem to know the exact details until the week of the show as the date kept flipping between the 8th and the 9th, and he said he assumed it would be free or very cheap but didn't know.
He said he was going to have some merchandise with him to sell so I made sure to bring some cash to support the guy, but he ended up not having any and after the show just signed pieces of paper (or whatever you wanted if you brought something). He was super nice and took a couple minutes to talk to everybody that he signed for. Listening to the people talking to him though, it was clear a lot of them knew who he was and were fans, because I had to listen to half a dozen stories of people seeing him or not seeing him at (insert con here).
