Google

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.
