A developer's weekend project to solve the problem of unknown website link previews went viral on Hacker News.
The project resulted in the creation of MetaCheck, a web app that displays how website links will appear on various platforms like Google, Twitter, Facebook, etc.
MetaCheck automatically fetches website information, fixes URLs, and shows previews on 9 different platforms.
The simple idea behind MetaCheck resonated with thousands of developers, leading to a viral response and positive feedback.
