I’m totally a sucker for this kind of thing, but it is so easy to get free stuff, and Microsoft seems to really like these kind of promotions. I remember very efficiently taking advantage of the great offers of Club Live three years ago to get tons of points and subsequent free stuff. Bing Cashback was neat and probably saved me a couple hundred dollars. Now Bing Rewards. There is quite a variety of rewards (you can’t seem them all until you sign up) but the best valued one is the 100 Microsoft Points for 100 credits (surprise!). Redeeming only those, I make about 20 cents a day, not counting the other current offers which I don’t know how often are updated.
The Bing Bar itself is not horrible. I’m sure more mainstream internet users would enjoy it.
