I'm a Norwegian expatriate living in Mexico City (for about five years now). I know Mexico City and the surroundings well, and also Norway, obviously. I work as a programmer, doing Python (mostly web and database stuff) full-time.
I have a personal page at http://www.avmaria.com/
I'm mostly joining to write about Mexico City, which I think is blatantly misrepresented in commercial travel guides, like Lonely Planet.
I was an administrator for a while, but resigned, since I don't have enough time to really do that work. I do work on the Mexico-related articles in bursts, though.
Additionally, and this is sort of off-topic, if wikitravellers would like somewhere to stay or someone to show them around a bit in Mexico City, I'm available, time permitting. Contact me for details.
