Capital letters give shape to lines of text on a page that make it easier for the eye to skim. Sure, they don't add any additional information that the period does not already have (and proper names are mostly vanity), but try reading page after page of all lower-case. It will take longer and comprehension will be lower. This is the same reason why some letters extend above and below the line - makes decoding words easier by giving them shape.

You can try it out yourself by saving this bookmarklet and using it to downcase a page! (Create new browser bookmark and paste "javascript:..." as the URL)

javascript:for (e of document.querySelectorAll('*')){for (c of e.childNodes){if (c.nodeType === Node.TEXT_NODE) c.textContent = c.textContent.toLowerCase()}}; void(0)

Come to think of it, the ease-of-read effect does look more pronounced on a full page of text rather than someplace where every post is a single sentence.

Perfectly fine until you need to talk about certain proper nouns that might be confused with regular words. https://en.m.wikipedia.org/wiki/Capitonym

It's very convenient when reading German, as you instantly know which words are nouns.

You do understand that written English is a descriptive thing, right?

That it's a result of trying to capture verbal communication in written/visual form?

Guess we should get rid of spaces too, since that doesn't reflect actual speech?

Put down the crack pipe, and step away from the computer.

Or (as others have said), "be the change you want to see"/"put your money where your mouth is".
