I was wondering how many of you do this:

I give out small digital versions of my pictures, with my watermark (of course) that are about 400 pixels longest size to my seniors for them to use on their myspace, facebook, whatever else the kids are using these days.

I have noticed that ever since I started doing this, my senior bookings have doubled, even tripled because of the free exposure this gives me. I also started another way to boost my bookings. I started giving each kid that refers another kid in to me a free set of wallets (48, costs me less than $10). This has boosted sales to crazy high amounts, to the point that I'm shooting 4 of every 5 days, and editing every day.

Anybody else that does this here? Does anybody else have any other good suggestions to make?
