And even if I didn't know the start and end dates, such dates are easily deducible by recent blog activity.  On the day ISM started, daily hits dropped by about a third.  Now that ISM has been over for a day, hits are up.  Way up - by over 50% relative to the norm as the hordes of practitioners lost in the glaring lights of Vegas find their way back onto the internet and back to their favorite blogs.  But I am curious - did any other bloggers notice such a significant effect on blog hits from this event?  And has any other event had such a significant effect on sourcing and procurement blog readership?
