Fun to see this on the front page! I worked on Yakread full time for about 8 months as an attempted startup, after a few years of other recommender system startup ideas. Now it's a side project that I develop on the weekends after my kids fall asleep, aided by caffeine (me, not the kids). I'm in the middle of open-sourcing/rewriting it. Hopefully will be done in a couple months? Then I can finally get back to adding new features. I talked about some potential ones in my previous post: https://obryant.dev/p/rewriting-yakread/
also I guess a link to the actual app wouldn't hurt: https://yakread.com
