What single marketing channel brought you your highest quality leads this season?

I hate to promote anything on here but Homestars is really killing it for me. I have 40+ 5 star reviews on there now and leads are coming in like crazy. I have even started to get a lot of invites rather than someone just posting a job to have other Pros show interest. I would say it is worth a look, but sometimes there are a lot of dead end leads on there. You have to pay attention to what is going on like how many other Pros have shown interest, how many have been shortlisted and how long ago the lead was posted.
