I'm pretty tired of having to zoom way in on every website I visit just to get text to a readable size. I think the size on these pages looks and reads great. I can count on one hand the number of times I've arrived at a website and had to zoom out because the text was too large.
Even Hacker News I have permanently zoomed to 125% and sometimes find it to be too small.
No, the grandparent comment resonates with me. I have good eyesight (when last tested, four years ago, it was better than 20:20) and use monitors with standard DPI on standard resolutions, and yet it suddenly strikes me that never in my life have I had to zoom out on a web page, and yet I frequently zoom in (including on Hacker News). Standard font sizes really are too small.
Not sure how much is age... I notice that reading my phone is often harder than desktop. I usually have a set of reading or computer glasses with me, but don't need them except for things that are close. Stuff on the phone always seems a bit small. Maybe there should be an effort to consult designers over 40 on some of these web sites/apps.
For Hacker News specifically: Verdana at 13px (12px for body text) was a fine choice at 72 dpi.
HN didn't exist in the 1990s, but its design principles are from that era. The look itself is a nice throwback, but the type size follows a technical constraint that no longer makes sense (it only made sense when CSS was nonexistent or very limited).

Bravo Mozilla, looks great!
