True, I really do like the rewards. But I really think Bing would get rid of them if it would was a good financial decision. And I think it would be a decent decision if Bing was doing better.
I'm sure that Microsoft has a great deal of data telling them that the Rewards program has a positive ROI, especially because a lot of the rewards are sweepstakes which essentially cost them nothing. Also, I have watched other people use Bing and seen four-digit numbers in their rewards count on the top-right. (It's agonizing, like watching someone who doesn't know about tab-completion use the command line.) This tells me that the number of people who use the Rewards is quite small and this contributes to its usefulness.
