Maybe it's a tangent, but Overleaf is hands down one of my favorite services.<p>It follows UX designer, Bret Victor's suggestion that creators need to be able to see what they're creating. It also has a ton of convenient features like forking, auto-saves, and inviting people to edit through private links without requiring that your collaborators sign up for an account on Overleaf.<p>LaTex creates beautiful documents, but it was too difficult for me to use before Overleaf. Also, I only use the free version of Overleaf.<p>Thank you for creating Overleaf!
