Does it really matter? While it may not adhere strictly to the rules of grammar, it's not so incorrect that it becomes confusing or changes the intended meaning. This is simply how language evolves over time.

I associate that variation specifically with non-native English speakers rather than a language evolution happening among native English speakers.

But you still understand it fine, no?

Why does it matter how you feel about language evolving(especially bringing race into it)?

[estebarb]

Kids born in "native english" change the language too. For example, treat irregular verbs like regular ones. Languages evolve with time, regardless of non-native speakers using it.

Yes, it really does matter. The concept that "language evolves" is absolutely valid when you're talking about the introduction of new words and phrases and adapting existing words to new purposes.

It's not the principle to invoke when you're talking about simply making logical mistakes. A question mark is used at the end of a question, not a statement. "How it works" is a statement. "How does it work?" would be the way to word the same CTA as a question.

Details matter because they add up to an overall impression of the quality of your work. Think of it as the "Brown M&Ms" principle, if you're familiar with that story. (Google it if you're not, it's a great anecdote.)

One part of effective communication is making things easy to understand and to remove stumbling blocks.

Removing uppercase or dots might still convey the same meaning but making it harder to read.

It may not matter that much but it does matter.
