I don't know if you've heard of it or not, but I really love Bzzagent. As a member of Bzzagent, I am able to earn some really great prizes (aka free Christmas shopping, lol) by trying out products and spreading the word about them. Everything I've tried is 100% free, as are the rewards I have earned.
Recently, Bzzagent added the Frog Pond. Through the Frog Pond, I am able to check out websites and spread the word about those, as well as share my opinions about those sites.
I invite you to check out my opinions on some great, and not so great, websites that I have found in the Frog Pond.
