I would like to say that I am very happy with something I'm seeing more of at GenCon - and its even more pronounced this year than it has been in previous years:
My first few years at the show, it really did feel like it was almost whites-only.
It's good because our hobby should appeal to people of every race, creed, gender, orientation, etc. And GenCon should accurately reflect the hobby.
I don't know if the hobby itself has always been diverse and GenCon was a poor reflection of the hobby (which is very possible) or if the hobby has grown more diverse over the last decade (which is possible, too).
It's weird - I feel like I'm treading on thin ice a little bit writing about this, because I am (mostly) white, myself. But I guess that's probably another conversation for another time (and probably another place as well, but no promises).
