Why it took a long time to build the tiny link preview on Wikipedia
> People seem to like it — we are seeing 5,000 hits to our API a minute to serve those cards that show when you hover over any link.<p>Uhm, no. It just means that people are hovering over links with their mouse. It does not imply any opinion about the previews.<p>> The original idea was conceived four years ago<p>When I was active at Wikipedia/Wikibooks 12 years ago, there was a user script floating around that did the same thing, except I'm not sure if it included an image. (Mediawiki allows a user to define custom CSS and JS that get embedded in every page of their user session.)<p>I don't mean to express dislike or downplay the hard work that went into this feature, just to add some context.
