How do you keep up HN post with more than 2K comments?

My HN reader has QoL features for reading such posts: https://hn.leftium.com/i/49630931?q=%22aspect+ratio%22

- Comments have 3 LOD (L:full, M:single line, S:collapsed)

- Optimal default LODs

- Simple to expand groups of comments (direct replies, comment thread ("spine"), full sub-tree)

- Highlight specific users like OP, or other interesting users

- Search for text within thread (automatically expands LOD)

- Highlights new comments (since last visit or set time)

It matches the way I want to read HN comments, anyways.

I don't. Once there are more than a certain number of comments, there's a diminishing value to additional ones because they start restating what's already been said in other comments.

Scan for high signal or value comments, read a subthread, collapse the subthread, as a "read" indicator. HN stores state in this regard for you, if logged in.

You are not required to read every comment on a HN submission.

Check for links using ctr F or something and yes no one can read all the knowledge in the world nor all the books in the world. We just read what we can
