It's like having a second, non-paying job with no days off...combined with having a puppy that I can't leave alone or it'll starve or at least crap all over my apartment. The worst part of the site is the group of assholes who constantly talk bad about me and/or the site yet still hang around instead of finding another place to cause drama. The second worst part of being an admin is people trying to shove their crappy uberweapons down my throat in the tech forum.
Being an admin or moderator (of any forum, not just here) is a responsibility and a workload...it's being a community member, role playing, and world building that make things worthwhile; I love my friends, the creativity, and watching the ongoing story unfold.
