Searchperks from Microsoft...

It seems the wonderful folks at Microsoft have introduced a program to encourage the use of their internet search services or portals such as MSN.com or Live.com. In theory it's pretty cool. Use one of their search services and earn up to 25 points per day. Then after accumulating enough points you can get "cool" prizes. The lowest level prizes which are ring tones and music downloads start at about 100 points. The catch, not only do you have to use the Microsoft sites which in and of itself is not too bad, you have to use Internet Exploder. No thanks, they can keep their "perks" and I will stick with Firefox and Google!
