Trust me I have tried ever writing site on the net. I have wasted precious time on many. On others I have found writing enjoyable and profitable on others. Here are some of my faves:

www.reviewstream.com: Okay, so it is no fun to write reviews.
This site pays you 1.5 for every in demand review and .30 is the bulk rate pay. The pay for these short reviews adds up quickly and as they rarely deny any submitted reviews it is easy to make 50, 100, 150 bucks a month. This is more than enough to pay you internet bill!
Best feature-cheaters' club-where all who plagerize will be announced for all to loath.

www.Helium.com-okay, so you will not get rich here, however you will gain exposure! You are paid a portion of their advertising revenue, and have a chance to earn more through ratings and however many times some one reads your article. You are advised to advertise yourself. The forums there are great!
Best Feature-user friendly site

www.associatedcontent.com-If your article is accepted for publication here, you have an oppurtunity to earn 3-16 dollars. That would make that the highest paying writing site at pres. time.
Best Feature-higher pay!
