As far as teaching, I got my first ratings at ratemyprofessor.com last semester (just looked them up). I'm hard and I give a lot of work. There's worse things to be.
I should make icons for "work" and "teaching".
Oh, and speaking of hobbies, I spend a hobby amount of money on Greatest Uncommon Denominator Magazine. :)
Just figured I'd see how these LiveJournal "writer's block" topics worked. Have you done one before?
