Three New Search Services: Wolfram|Alpha, Microsoft Bing, Google Squared

It has been a wild few weeks in search engines — or search-engine-like services. We’ve seen the introduction of no fewer than three high-profile tools … Wolfram|Alpha, Microsoft Bing, and Google Squared … each with their own strengths and needing their own techniques — or, at least, their own distinct frame of reference — in order to maximize their usefulness. This post describes these three services, what their generally good for, and how to use them. We’ll also do a couple of sample searches to show how each is useful in its own way.
