Very old, but I wanted to post that I've found the exact same issue. I find it accessible, especially when I do some research, but so far no one I know has shown even the slightest interest. I've mentioned it to two friends, both of whom I consider very intelligent, but neither took the bait. My female friend loved HP MOR, though.

I'm another data point (16 when I first started reading) who found it very accessible.I've tried a couple different ways of getting my friends interested, with varying degrees of success. I think the problem with getting most people (regardless of age) interested in a site like this is that you have to expend a lot of time even to understand what everyone's talking about, and it doesn't seem worth it "just for a blog".
