It would be nice to make FAQ 60 address whatever limitations the Directory has on searching, since the interest searches from clicking an interest in the profile currently go there. I'm not sure how it picks which journals/communities to list (is it still first X number of people to list an interest, like /interests.bml is?) Also, it seems that the Directory's limit is 2000 for interest searches, as opposed to interests.bml's 500 of each.
(Also, note to self, the Interest Format section could use some tweaking. Add a bit about "Interests must conform to certain formats", or move "if you don't want to blah blah" to the end of that section. Length should also be 50 characters *and* 4 words, since even 4-word interests are restricted to 50 characters. Most of those read kind of awkward.)
