a) Provide interesting content for your users which you don’t need to create. b) Build relationships with other bloggers – if they guest blog for you, you may be able to do the same for them. c) If you work it right, you may be able to get a referral link back to your blog from theirs.
The guest blogger’s incentive is to get links back to their own blog/twitter/facebook etc
You’ll want someone who can offer complementary content to your own, and someone that has the level of quality that you require. You can also set standards e.g. set picture size standards that they have to adhere to.
Hope that helps!
