I am having a hard time getting my affiliates to actually DO any affiliating. Before writing my ebook I contact about 50 people in my niche who were all very excited to help promote my book. I gave them all free copies with the book and they made more promises they would blog/facebook/tweet about it. That was several months ago and to this day my only active affiliate are through Clickbank's recruiting process. Part of the problem might be that my niche doesn't know much about the affiliate process even though I gave them step by step directions.

What has worked for you in motivating affiliates to work?
