Yahoo Search Offering Incentives?

Brian G. writes: “I guess Yahoo Search is considering offering incentives to users that make Yahoo their primary search engine. Some of the responses I have seen so far are showing mixed reviews.

Have search engines, like Yahoo, reached the maximum amount of resources users need and want or can they no longer make improvements? I would think further development and improvements would be better than incentives, and last much longer in the long term in keeping users.”
