I am too young to remember stumbleupon, I think they were sold to some big company around my birth year ( 2006 ). That is all I know. It is way more chill than most popular social media apps. And that is something you should appreciate.
I love this! This basically replaces the need for any kind of email newsletter, and helps reduce your online research on any topic. I've put it to the test, and it performs quite well. Congratulations @kensavage + team!
