After about a year on the SE I have noticed that the number of views for any puzzle range dramatically from less than 100 to 5K or more. I assume a puzzle is consider viewed when a reader clicks on it? So what makes someone click on a particular puzzle? The puzzles that get over 1K views: Are they viewed because some other sites catch them? Or is it just word of mouth? Are there puzzle solving groups that spread the word about a good puzzle?
