Apparently this (warrenellis.com) is starting to make the rounds. Ellis posted to his blog about the SD Comicon, and then Joss replied in the comments, and if you're a fanboy you might enjoy the ensuing flamewar. I particularly liked the running gag of X-jokes.

Depends on what you're going for. I'm usually there to buy comics, and other than the person who didn't bathe that morning, there's not too many problems. Keep to yourself and devise a mission to accomplish for that day, and you should be fine.
It is a good rule in life never to apologize. The right sort of people do not want apologies, and the wrong sort take a mean advantage of them. P. G. Wodehouse (1881 - 1975), The Man Upstairs (1914)
I'm not really involved on the publishing end of things, but from talking with many people who are, I think the best advice is assuming that you won't make any money at it. Most print books don't make money, and many don't even break even.
