A contributor makes an edit on a long-dormant entry, and the entry jumps up into the "Recent Changes
" page. Suddenly, the entry accrues a number of unrelated edits; a number of contributors had forgotten that it existed, and now that it's back on their radar, they have something to add. Sometimes the phenomenon is inverted - a mostly useless page is launched without YKTTW
and sits on the site unchecked until an edit is made out of the blue, then the page is cutlisted.
