This is a list of a few "get paid to take surveys" programs that I have had some sucess with in the past. I have not gotten paid much, probably no more than $30 in one year from all the programs I have tried...combined. I do not recommend them unless you really like to spend a lot of time on the net. Also, from my experience, the ones that offer referral bonuses seem less reputable than those that do not.

Program Name.	Referral reward?	Comments.
American Consumer Panel.	No.	One of my favorite. I've gotten paid the most by these guys.
Savvy Survey	Not sure.
Synovate.	No.
Greenfield.	No.
Gozing	No.
Opinion site.	Not sure.
Kelly Research	No.
NPDOR	No.
