Where do you get your referalls?

first i would try a few friends, why not? especially if you know their email. secondly try forums or anything related to this, maybe some myspace people if you are on that site. I have gained my referrals by posting it on my blogs. I have 3 that have earned me nearly 4 dollars in the past couple days. http://blogaboutyourblog.blogspot.com/ I just posted it here and got some referrals.
