We've been curious about this for a very long time and never seen a good answer:
Why do some people capitalize every word they type? We see it _all the time_ and I'm wondering if it's a case of people not familiar with the Latin alphabet (or just alphabetic writing in general) misunderstanding some rule?
If anyone has any idea please do reply to this, I'd really like to know
@daylight The guess about it being a second-language thing is because we almost always see this in conjunction with other hints that english isn't the person's first language; subject-verb agreement errors, non-idiomatic phrasings, etc
