I have been searching the web recently to find fun things to do, here is a list of all of my favorites they are rated (from one to ten) and I tell you the good and the bad.
 
Freeride
Summary: Freeride gives you points which may be used as cash to buy many things online like magazine subscriptions gift certificates etc... You are awarded points for visiting sites "called destination points" signing up for free services or sending in UPCs. It has a nice interface, and updates your account in real-time.

Mypoints

summary: Earn points for visiting sites and signing up for free stuff, if you have a minimum of 1000 points then you can use the points as cash to buy many things, similar to freeride, but mypoints has more choices.

Cybergold

summary: The idea behind this site is similar to the others, except you are paid $$ that can be sent to your account. The money generally not more than $0.50 can be credited to your credit card or your checking account. Where this site really shines is it's "mad trivia" a daily trivia game where you can win cash prizes.
