I noticed a surge of 6 upvotes on an old answer of mine on stackoverflow.com over a weekend. This seems unusual, provided it was just a subjective survey question, so I'm curious to know how this happened. Did someone link to the question from a forum, causing a spike in upvoting to various answers? Did someone point out my answer specifically?
Googling "link:URL_to_question" returned no results.
Is there any other way to satisfy my curiosity?
