  (In reply to devmonk) Interesting, I never read that, but now I'll have to see if I can find the study you talk about. Like I mentioned before I would rather increase the font size and then space things out a bit more, but that would offer less links on a page so it becomes a compromise. Thinking of the type of audience HN attracts one would think people wouldn't have a problem bumping up the size in their browsers although that can be annoying to do.
