Hello,
Given the conclusion, I am afraid I do not really see the interest of having this thread in third position in Bing results.
The one that has surely been opened on forums.asp.net afterwards would surely have been more useful.
Maybe a flag in forums could point out the status of the thread, such as : opened, solved, out of topic, and maybe others I do not think to now.
Using that could justify a reflexion about the search engine user interface.
