A new Chrome extension has been released that visually highlights Hacker News submissions and comments related to greg.technology and its subdomains. The extension also flags posts and comments made by Greg Sadetsky, a frequent contributor to the site. When a match is found, a small orange badge featuring Greg's face appears next to the relevant content. Additionally, an animated Greg character dances in the corner of the page, displaying a count of how many such references are present. Users can interact with the badge to receive explanations or click the dancing Greg to trigger more animations across the screen. The extension requires no special permissions beyond running on news.ycombinator.com and can be installed by enabling developer mode in Chrome and loading the unpacked extension files. This tool offers a playful way to track the presence of Greg's contributions and links on Hacker News, enhancing user engagement with the community's content.
