As far as authority goes, there’s no backlink like a .edu backlink. Getting one though, is kind of tough. But as MartiniBuster’s Roger Montti points out, even artsy/nudie/sortaporno site SuicideGirls.com has a bunch of .edu backlinks. So maybe they’re not out of the question for your site, too.

Very Nice Advice, still .edu links are tough to get. Sadly most of the .edu pages are abadoned and have not been updated for years. Once those are still updated are rare to find.
