No one will mistake your posts for LinkedIn slop. You actually have something to say, with coherent arguments presented in paragraphs containing multiple sentences.
If you want sentences without capitalization to be your thing, then go for it. It's just a weird hill to die on, taking away from the readability of your posts for no real reason.
In all honesty it's just never bothered me before and i've havent met many people bothered by it either
It's the same thing with dark mode as default, i chose it because it's my own preference and i'd love it everywhere, but i'm constantly being flashbanged by phone apps because someone decided #FFFFFF is a good background color while the app is loading.
It's your personal style. Researchers have their quirks, don't listen to the industry suits saying dumb shit like "it's unprofessional" you can mask if you're looking for a job at Google in the future, but for now enjoy being yourself and say fuck you to the lazy socially imposed dogma of this particular community
i see enough slop and Look At Me on a daily basis. i don't want it to look like an ad or a LinkedIn post in 2026.
