Microsoft provides incentives for people to use Live Search

It's called SearchPerks!, and it's actually a pretty neat idea. You add the toolbar to Internet Explorer, and it clocks your searches made through most different types of Live Search searches, through Live Search, the MSN home page portal, and other search tools. It claims to not track the words you use or the sites you go to, but I'm sure it's stored away in some server somewhere. In reality, though, whatever you search for and whatever sites you visit are logged, so don't let that deter you from participating in this program.

So that people don't abuse this program, the limit for ticket earnings is 25 a day. You get 500 tickets immediately just for signing up. Here's the list of prizes that are redeemable after April 15, 2009. There are some pretty neat prizes, but I plan on choosing the last option at the bottom: Give Tickets to a Preferred Charity.
