What do you want from a search engine? Bing is the one search engine that rewards you with money for using it. Sure, it takes time. But with a bit of dedication and regular use, you can earn money to spend on movies, music, video games, food or even get discounts on Amazon. It took awhile, probably 18-24 months. But I recently had 50,000 Bing points built up. Which pretty much translates into $50 cash. Just for doing what I would be doing ordinarily. I cashed in my points for $50 on the Windows or Xbox store and got the new Forza Horizon 3 for $10, the retail price is $60. The alternative I was thinking of was a year of Xbox Live a similar amount of points. So you really can't beat that. Free stuff just for browsing.
The only thing I would like to see Bing add would be a shopping search function like Google has. It would make it easier to track down hard to find items and sort by price. Usually for that I use Google. So if you're reading this Bing, add that feature!
