I haven't seen it mentioned before, but has anyone considered doing a feature article for any colleges' online publications? That's a good way to not only get your site noticed and improve its traffic, but you will also gain credibility. Not only that, with a "welcomed" link to your website, you don't have to worry about it ever being deleted. Plus, you stand the chance to have that same article syndicated in other college publications, which would naturally lead to more .edu backlinks. I suppose that I may be looking at this from a writer's standpoint, but I think that this same principle could be applied to other industries as well.
