Could you use interviews with people who are seeking publicity as your content? (Particularly university professors who publish books or journals or something else they want to publicize?)
I'm just thinking that if you could interview them and put that interview on your site (or content derived from that interview), then they would probably be happy to link to that article (or to your home page) in an effort to promote themselves.
I know this would require a bit of work, but maybe it is a way for sites to get both free content AND a .edu link
Having said this, I think I am going to start contacting some of the small publishing houses in my niche and see if I can get them to hook me up with some authors. Hopefully they have some high PR sites.
