I found it interesting because:

It's accurate in ways I didn't expect.  I do like Boiled in Lead but only learned recently that I do.  I am not precisely a fan of Sacred Harp singing (beyond being generally interested in American musical traditions), but that's a pretty offbeat interest that's shared by several people on my friends list, so it makes some sense that it would pop up.  I never would have thought to put "cool hair things" on my interests list, but now that it has appeared I can't imagine why it escaped my notice in the first place.

I don't even recognize some of the people it lists.  Steven Brust?  China Mieville?  Mun?  Wilkie Collins?  I am sure that I had never heard of these things before seeing them on this list.  Even now I am not sure what "mun" is supposed to be.  Perhaps I am interested in it, but I suspect that I may never know for sure.
