I had some success with it a few years ago, when it was first introduced, but didn't like the type of clients that it seemed to attract.  Since they advertise with "Let Agents Compete for your business!"  most prospects won't respond to you unless you promise a very discounted commission rate.  Originally, Homegain had a $99/year program, but later changed to a referral fee.  With the referral fee (35% ???  - I can't remember, but it seemed like a lot) it just wasn't worth bothering with. 

I would rather spend my "hard earned money" on pay-per-click, or professiona SEO work.
