This is not because I’m super cool, it’s because I’m an old man and I’m still typing in 2025 like I was typing on IRC in 1998 when nocapsing was absolutely dominant.
But if I type in a space where proper capitalization is expected, like HN, I do it (this was typed on my phone with no autocorrect, suggestions or autocapitalization — I know, I’m dumb and my opinions and settings are wrong). If it was my personal blog however I would do whatever I felt like doing.
