Bing provides helpful code snippets within results for developers focused on MS tech
I noticed that Bing provides code snippets extracted from MSDN within search results when you query for programming topics related to Microsoft technologies.
It prioritizes results from the Stack Overflow forum to show questions which are resolved. What I especially loved was that Bing shows a date next to the link (though it is not clear if that date is day the question was resolved. For the question "Why seal a class?" the date indicated in the search result doesn't match any date on that page). As technology evolves constantly, I strongly feel that all technical literature should have dates as they provide context to the content. It is sometimes possible to guess if the result page could be stale.
If there is a recent tweet corresponding to your search keyword, it gets that too -
Way to go, Bing!
