We are always counting what we do so that we can report on the state of things in the library world. As with any sort of statistical presentation, we apparently only count certain things, rather than attempting to accurately portray the work we do every day.
Statistics are like a bikini. What they reveal is suggestive, but what they conceal is vital.
In the case of libraries, for some reason we want to conceal that we are helping people with questions galore, but not apparently reportable, fascinating questions.
In my opinion, we should count every person we help. They matter. Their questions are important to them and they trust us to be able to answer them, large or small. If someone cannot get you to answer a simple question for them, why would they ever think you could answer anything complex? DOH!!!
