I know MSN has been leveraging their properties, including MSN's Encarta Encyclopedia but never really noticed it within the context of MSN Search. Last week a wrote an entry on Question & Answer Search Engines, and I referenced Ask Jeeves, BrainBoost, left out Answers.com, but I did not mention MSN. Yosef Hass commented that MSN is using a form of Ask Jeeves's Smart Search to embed answer's directly into the search results.
The example I have given in the previous entry works well at MSN as well: When was ben franklin born? and Who was the 27th president of the United States?
I have updated the Cre8asite Forum thread with this information.
