Nerd works. It takes one to want to be one. It's self-depreciating enough to be P.C. and not too "elite". Although what's wrong with elitism. Shouldn't everyone want to be their best? Maybe it's the "ism" that earns the "jerk" title after it because it implies exclusion. But geeks don't really exclude anyone who want to be included. You just won't have fun with somethings nerds find satisfying and exciting. Educational enthusiast? Information addict? Curiosity driven, Nosy know-it-all's anonymous. Relentless student.
