Google

Google ignited a bit of a firestorm when it claimed that Bing was poaching its search results. To test their theory, they baited a honeypot and caught Bing with its hand in the jar.

Criticisms of Google data aggregation and privacy policies abound.  In hopes of stemming some of that negative press, Google recently announced the Google Dashboard, to “offers a simple view into the data associated with your account.”

Stephan Wolfram recent announced his latest endeavor: Wolfram|Alpha.  Where Google will search the Internet to answer your queries, Wolfram|Alpha will calculate the answer.  Where Google gives you 287,000 results for "what is the longest straight road in America," Wolfram|Alpha will give you one: the answer.

At least, that's the plan.  We won't really know until May.
