i found two good reward sites that i want to shared from my experience.

The first one is best to get free domain and hosting, domain is .com, .net, .org and others. How you earn the domain is through filling in free surveys that take the most 10minutes and other ones are short about 4minutes. I earned my domain while spending a week to do it. That earned me a free domain as for hosting, that site provide free hosting when you requested to redeem the domain. I used the hosting for two years and nothing seem to happen, the guy who made this site is very friendly he replied my email within a day. there are also other rewards such as giftcards and ipod but i never made that far. The second one is a review site, you earn points by posting review and picture about places, and earn when people rate it. it is a very friendly community like MyLot, is useful when browsing places you might want to go. The reviews do not need to be long about 20-50 words, there are 3 goodies bag you can redeem one is t-shirt, candy and a cup, second bag is a Frisbee and a 1G usb, and the third is the best is a ipod shuffle and a soft toy. I got all three goodies bag when i joined that site for just a month and a nice site to check out. If you are interested i can always reply you and sent you a message to check it out.
