I was on a conference call with my Research Director, Mike Gilpin and colleague Charles Brett the other day discussing complex event processing and business rules when suddenly Mike and Charles starting talking about "horses for courses". Say what? We went from talking about events and rules to horses and courses? I never heard this expression before so I asked. And, for those of you who think that I am provincial, I asked several other people in our Cambridge, Massachusetts office and they were dumbfounded as well.
