Bing getting a fall refresh by Ina Fried, Beyond Binary (Nov 11)
Has a list of improvments at Bing this fall.
+ Hover - it's not new but "Bing's hover result will now feature more information including a thumbnail preview of the site in question. "
+ arrangement with Wolfram Alpha to get some data - nutrition and math calculations.
+ "improved local results for topics such as weather and events." (US)
+ Bing gets the MSN Video site
+ easier handling in Bing maps
These mostly relate to the user interface rather than aids to help the searcher refine a query.
