Has anyone here ever tried Winzy or Blingo before?

Basically, Winzy is like google, only everytime you make a search, you earn a chance to win prizes (Blingo is the same, butis only available in US). From what I've heard the whole thing is pretty legit and winning a prize is actuallya common occurance(prizes range from Amazon gift certificates, to Ipods, to $1000). I personally haven't won anything yet, because I've only been a memberfor afew days.

This isn't spam or anything, I'm seriously just curious. Has anyone ever used a service like this? If anyone's interested there's a link in my sig (I could use more friends :) ).

How does it work? As in how do they make any money? Ads?pandadude01

Yeah, it's like google or ask.com. There'sa little "Sponsered Links" section and that's where they say they get their prizes or money.
