Vitalizing Edit

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 trope is inverted—a mostly useless page is launched and sits on the site unchecked until an edit is made out of the blue, then the page is nominated for deletion.
