I love every article that comes up on HN/reddit about typography and fonts because the inevitable onslaught of "I find X unreadable and Y delightful because of Z" gives me new fonts to try.

There is some objectiveness to this subject but damned little and 99% of the comments are opinion. As a developer of many years, I've learned to just skip over any post that uses any form of the 'readability' adjective. It's totally subjective, and the poster more often than not will have a religious fervor about their opinion.
