Went to the gym again last night, and it went much better than the previous time. Managed to do 13 climbs, though not very many overhangs. (They'd just redone a lot of the climbs in the overhang section, so it was kind of crowded with people trying out the new stuff.) I cut short the number of pull-ups because there was only one cross train machine open and i was afraid someone else was going to grab it, but i did 1308 calories on the machine, so that's good.
On a very related note, catbird convinced me to sign up for Fitocracy, which is kinda like FourSquare for exercise, but modeled a little more like a game. You get points based on how much/what kind of exercise you do, and you level up. If anyone else is using it, or just wants to check out my profile, here it is.
Edit: Hmmm, apparently if you don't have a Fitocracy account, that just takes you to a login page. How annoying =P
