... although I don't know that I'll ever use it instead of Google.
Newssift is aimed squarely at business people, and has some features that it thinks will prove to be of meaningful use to businesspeople. This includes contextual search, source identification and sentiment-tracking. The last bit apparently tells the user whether the search-term in question is "favored" by the business at large.
I don't deny that these features are useful - useful enough to wean me away from Google is another story.
What do you do when the business is so lucrative, and the currently dominant player so... dominant?
Keep trying, I guess. Good luck, you guys.
