On the home page for Geocaching.com there is a small section that shows "There are 596867 active caches worldwide." and the number of cachees logged in the past week, and the number of cachers that made those finds. I would find it more interesting to see the number of cachers that have logged some minimum number of caches over a longer time period. This would eliminate people that try it once and don't come back. Let's say the number of cachers that have found 5 over the past 3 or maybe even 6 months. I wouldn't expect stats like this to be run daily, maybe even once a week would be sufficient. Oh, keep the short time numbers like now, but just add the new one.
This would show what the real activity is like and reduce the 'noise' numbers not only from one-time 'try it out' but also would even out the low numbers that result from weather (it's been over 95 here most of last week), vacation (when the family says -'be with us!!', business travel (and the boss is along, or company policy dictates free time- or lack of it), etc.
