When I see that a question has 1067 views, is that 1067 separate people, or maybe 45 people many times? Or maybe even 1 view per person per day is counted. What does the 'views' number mean?
waffles has answered this:
The view count is not increased for the same IP address, within certain thresholds.
However, if you visit a question 1 day later, the count will probably increase, even if we saw the IP before.
Tracking IP lists per question would be a bit on the expensive side.
