That might equally be a stylistic choice, but I my gut says it's not.
Any special reasons? Just because I like to know people through their choices and views. Didn't want to sound rude in the previous comment, so if I did, genuinely sorry (non-native speaker woes).
1. writing in lowercase is freeing. it reminds me that grammatical rules are arbitrary, and by extension other rules. "you can just do things."
2. people who are pedantic about this when it's clearly intentional are probably not people i want to interact with anyway, so it's a good anti-asshole filter (https://siderea.dreamwidth.org/1209794.html)
frankly i don't want a larger audience, i didn't expect this to hit HN. i hadn't thought about it being harder to read for people in the project though, i'll do a poll on whether they find it distracting.
