Speaking of manpages, during a different hn convo, I found out about mansnip [1]. It is for when you remember the command but forget what the flags do and has been very useful re: "I keep using curl -LO, what is that doing again?" etc
The interface also allow to comment, post and interact with the original HN platform. Credentials are stored locally and are never sent to any server, you can check the source code here: https://github.com/GabrielePicco/hacker-news-rich.
