Hi.
I'm a 24 yo male grad student (in Halifax, Nova Scotia) studying ecological math modelling.
This site is a gold-mine for clear thinking on the relationship between maps (models) and territories (systems). I'm interested in understanding and dealing with the trade-off between fidelity of the map to the territory and its 'legibility'. I've been lurking for about a year after coming across an article by Eliezer via Hacker News and got hooked.
No kidding! Haligonian lurker here too.
Some research says that lurkers make up over 90% of online groups. I suspect that Less Wrong has an even higher percentage of lurkers than other online communities.
Please post a comment in this thread saying "Hi." You can say more if you want, but just posting "Hi" is good for a guaranteed free point of karma.
