I liked the idea but have to say I’m not a fan of your design. It just feels a little rough. Also I expected comment chains to be collapsible. I also experienced long load times for articles (>5s, some >15s) which is way to long. The first article I read only showed a completion of 77% although I read the whole thing. Not sure how you determine how much has been read but I assume I’m just reading faster than what you’re used to.

Yo - this could be a good idea but I wouldn't be able to tell (apparently) since I can't view any of the content without either downloading an app or signing up.

It might be a better policy to show visitors the top e.g. 5 - 10 trending articles on readup to get them 1.) to get a taste of what's shared and 2.) see if that's any better / different to what they'd find on hacker news (which can be read freely).

Anyway, good luck!
