so then. I just went through each entry on my friends list, and added a few interests of theirs to my list (easy to do now that they have the "edit yours" link at the end of other people's interests) that I didn't share with them allready (with one exception). Jumped my interests list from something like 30 or so entries to over 70! And I left a lot off, because I figured it'd be just silly to list them or I just don't feel like going and listing all the subdivisions of a general category that I'm interested in.
Definately gives a somewhat better view of me, though, having that many interests listed.
