Hey Slackers It is not a bad domain name. Although it is a .org extension, that is not necessarily bad. My problem with this domain is the fact that it contains the term Bing inside it. This may have severe consequencies when Microsoft decides to take action. The owner will definately loose the domain. If you can get written permission from them to make use of the domain, the domain may have some good value. For you to get permission, you will need to have an established site. Work on that, get permission, launch the site and we can look at the value again. But, as for now, I would have to say the domain has no value at all.
With that domain, I would get some content on it something like top ten tips for ranking on bing. Stick google adsense on it and see what the traffic is like. Let it site for a year and try sell it for a couple of $100.
