If I browse recent questions on Stack Overflow, I see that mature questions (a day old or so) tend to have a number of views from a few dozen to a few hundred. Except for a few which have thousands. There doesn't seem to be a smooth distribution - I rarely see questions with 500-900 views, for example.
How come those few questions get so many views? Are all those views coming in from searchers or browsers on Stack Overflow? Or are they coming in on links posted to external sites? Do we have any information about this? Any anecdotal evidence? Any wild-eyed conspiracy theories?
To put it another way (or perhaps to ask another question), if I was a shameless rep whore, should I be posting links to my questions on other sites?
