Hey ho all. I'm based in Canberra, Australia (and New Ireland, Papua New Guinea), do website development/design for a living, engage in climate change discussion a lot, and ended up here by the circuitous path of stumbling across "Harry Potter and the Methods of Rationality". Marvellous piece of work, which I found quite resonant. I'm very impressed with what I've seen so far of Less Wrong.
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.
