I have been doing eRewards for almost a year and generally receive 5-7 a week--one almost every day. There was a little lull--maybe December and January where it dropped down to one a week or less, but is back up to normal now.

I am female, over 35, work full-time for a financial institution, and have a college degree. Most of the surveys that I "qualify" for seem to be for retail type products/services...beverages, shopping, makeup, travel (lots of them), and phone services. I do not make it very far on any IT or media-related ones. At the end of any where I do not qualify, I always click the "more" button and give them more info about me. I think this helps get more opportunities. YMMV
