Went to the Phoenix Comicon 2010 over this past weekend and had a blast. Bought the full-access tickets and were there Friday-Sunday (could not go Thursday – oh well). Met some very informative people, some who are relatively new to the business and some who have been in it quite a while, and yes there were folks dressed up in costumes and having a lot of fun with that, but what I was most impressed with is how relaxed and open everyone was whether they were famous or not (or maybe not famous in my very small sphere of interest).
The whole experience was exciting and fun and encouraging.
