I would love to expand it to other sports, the only real challenge is finding an API with appropriate stats and writing a simple algorithm to decide what constitutes "watchabilty" based on the those. I would happily take advice on that re: UFC and add it to the site
A software developer and football (soccer) fan who lives in an antipodean time zone, I enjoy watching games on demand the morning after they occur. Apart from watching the games of the team I support, I like to watch one or two of the most entertaining games in any given week, but score spoilers absolutely ruin the experience for me.
So, I created https://laterball.com: a web app the algorithmically determines the best games of the past 7 days without score spoilers, to let me (and you) know which games are worth spending time watching. There was also an associated twitter bot at https://twitter.com/laterball which occasionally tweets when there's been a high-quality game until the recent Twitter API changes.
Technical stuff: the back end is a Ktor server hosted on a linode instance which pulls statistics data from an API to determine the ratings. Factors used to determine ratings include goals (number, timing, swings in score, comebacks), xG, wins or draws against the odds, cards, and a few others.
