I've been an admin here at the Wiki for more than a year, and a KoL user for several years (I still remember how happy I was when an earlier character of mine sold a gasmask for a whopping 50,000 meat!). Out there in the mythical real world, I do a lot of reading, running both a literature book group and a science book group. I'm also in a history book group, but, like many KoLers, my real passion is science fiction and fantasy (my tastes are on the literary end of the scale). Drop me a note if you want to talk SF&F!
I did an analysis ages ago in the pre-ascension days that tried to determine how happy or unhappy players are with a particular class once they start playing it. It's awfully dated by now, but here it is if you're interested. The accompanying graph is viewable here.
