BI vs Mashups Analogy

"The difference between BI and Mashups is the same as the windows in your
car - they are similar yet they serve different purpose. BI, like your side
and rear windows, provides a lot of info about what has passed - but you
would never drive by looking only out the sides and rear. Mashups, like
your windshield, give you real-time info so as to make timely decisions
based on what is happening now. All of the info combined allows you to make
the necessary corrections instead of making misinformed choices based only
on the past. See, they are not competitive, they are complementary!"
