If you're interested in a backlink, post swapping is the most beneficial for both parties when both sites have similar traffic mangitudes. Compare your site against HackCollege at compete.com. 

We hold post swaps to the same standards and rules as open-submission guest posts except that we trade one backlink. Note, especially, that guest posts must be an exclusive piece of content -- no re-posting on your own blog and nothing that's already been published.

If you don't want a backlink, just submit a guest post. Or apply to become a writer.
