It's fine. On my screen (Windows 7, latest Chrome) it's a readable serif font with decent contrast. Text is sharp, though I personally don't favor serif fonts for main text.
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?
Win 7 here, Latest FireFox, LCD monitor at 1680x1050. Just looks blurry to me, but by comparison reading HN (or dozens of other sites today) hasn't been an issue.. nice and sharp. Don't think it's a case of PEBKAC... but maybe. :)
