I applaud comics creators who don't charge for their signature at conventions where fans are routinely paying $50 and more for "celebrity" signatures. Maybe those creators have steady well-paying work. Maybe they receive large royalty checks on a regular basis. If they are artists, they may be making hundreds of dollars per piece for original art or drawings. But not every creator has that option. Some creators rarely get a lot of work, much less well-paying work. Some creators may feel they deserve a few bucks for their signatures and need that money to pay convention expenses. Or need the money to pay bills. Or are simply trying to create a cushion between the lean periods and their constant bills. If you're not charging for your signatures, that's definitely a nice thing to do for your fans. I really do applaud your generosity. I just wish (some of) you didn't act so damn superior about it.
