There is another article at Zach's webpage
But basically it's this.

Blingo is a search Engine. When you use it, it uses a Google powered search, BUT you could win stuff. If you become friends with people, then you and your friends win the stuff.
It is as simple as that!!!

So go ahead, clicky clicky, and Be my friend!

Nothing to it! You use Blingo instead of Google, and then you win free stuff! Sweet eh?
