Hi. UK lurker. Found Overcoming Bias many years ago from a link from Scott Aaronson's blog. Have been reading ever since. In case you're interested in demographic stuff, I'm a stats geek working in a finance firm. I'm very interested in Bayesianism in its application to finance.
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.
