So many contest sites...

Have you noticed just how many sweepstakes and contest sites there are all of a sudden on the Internet? Just in the past few months, there have been a lot of them opening up and giving away some pretty incredible prizes, including cruise vacations to the Caribbean, plasma TVs and much more. They all operate on different variables but have caught the attention of bloggers who are signing up themselves and getting others to sign up as well. Since all of them are free, you're not losing anything at all by joining, only increasing your chances to win!
