Written communication is hard, and one of the keys to good written communication is leaving as little room for misunderstanding as possible. Using proper capitalization, spelling, and grammar are a few of the ways you can make your text more readable and less prone to misinterpretation. That being said, there are plenty of reason to eschew writing best practices, and you have to be pragmatic about it (for your own sanity, if nothing else). Have a hand injury? Skip the shift key once in a while if it saves you some pain. You're trading readability for speed/comfort/whatever, but depending on the situation that might be the better decision.
