I also found this blog through HP:MoR.

Now that I think about it, I may have found HP:MoR through this blog. (I don't read much fan fiction.)

I can't remember anymore what linked me to HP:MoR, but I think that I got there after following a series of blog posts linking to blog posts on blogs that I don't ordinarily read. So I might well have gone through Less Wrong (or Overcoming Bias) along that way.

But if so, I wasn't inspired to read further in Less Wrong until after I'd read HP:MoR.
