Fanfiction.net is a niche. None of my scifi loving, tech friends are aware it exists. And neither did I (or was barely aware or it, anyway), until you just mentioned it. I'm not young either, and I'm more online than the average (I know of Something Awful, Slashdot, 4chan, etc).
A while ago, a friend told me about Harry Potter's Rationality fanfic and he didn't know who Yudkowsky was, he just thought it was some random author doing a parody of HP. LessWrong is of course very niche, my friend didn't have the faintest idea of what LW was.
