Is it just me or is the OP's page font very difficult to read? On my system it seems low contrast and blurry, almost out of focus. I had to abandon reading the post by the 3rd paragraph, ironically because my eyes couldn't handle the font choice.
I always wonder at all these HN comments about impossible to read sites, is it the computer, the software, the display or the thing that sits between the keyboard and the chair?

Better question, how does one test for this kind of thing?
