I've realized that it's hard for me to remember many of the comments I have read on HN, or Lobste.rs.
I can remember the articles and that are linked, but not the discussion about the articles. This sucks since the discussion adds nuance and background to the article that is helpful.
Have other people noticed this, and if so, why do you think it happens? Is it a UI issue (maybe mental energy is wasted keeping track of where we are in the comment tree)? Or is it a cognitive issue (just pay more attention)?
