While the total unique visitors from the last 30 days is a very helpful stat on the home page, I recently watched the count go from 81 to 79, as I moved past the day in the last 30 where I had 2 visitors, even though today I had 2 views, so it subtracted and added the same amount of visitors. I started today with 79 and got to 81 and then back to 79. Another helpful stat on the home page would be how many visitors I have in a 24-hour period, maybe starting from 12am server time to the next day at 12am? It would then return to zero. This would give a contributor a better idea of the number of visitors drawn the site.
