Hello, I'm Simon. I'm studying a PhD in Economics. I cannot recall how I first began to read your blog. I don't manage to read everything, but I appreciate what I do read as it is often outside of what I customarily read. I don't find I have the time to comment properly as I'm spending time on research and teaching and coherent comments would be beyond me I fear after teaching undergraduate microeconomics for three hours.
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.
