I don't care how long you've known the language, just show me the source.

I'm frustrated. Every second post in this sub is a super broad and subjective "What are the hardest/easiest/most annoying ______ in a language?" post that don't lead to anything interesting because people don't back up their answers with sources. And the answers just devolve into either anecdotes or a popularity contest between answers.<br><br>If you've somehow known a language from before you were 3 months old and have some profound insight, that's great, but either back it up with a source or don't say anything at all.
