I don't understand exactly how this is low-friction in any possible way...
1. Open browser -> Go to devhints -> search for "dd" -> select doc
2. Open term -> type tldr dd
Another thing that is missing is offline access, localStorage integrates in minutes...
I simply feel like this is someone trying to reinvent the wheel and also that this medium (a website) might not be the best way to do that. Sure it has a pretty frontend and a somewhat decent user experience for a web "app", but I (and probably many more devs) spend about 90% of my day in my terminal...
