What if we required that people leave videos instead of writing up issues? I'm not seriously proposing that, but it's harder to be a jackass when speaking than writing. Especially to someone's face.
Funnily enough I often have the opposite issue. I will sometimes start writing up a bug report, spend a couple of hours trying to get my thoughts down on paper, then give up because I have neither the time nor energy to finish. I kind of wish there was an option to submit a voice recording along with some code snippets :(
True, it's not really a workable idea. My point is that text communication encourages jackassery, and many people don't think about that until they consider just how ridiculous or obnoxious their words sound when spoken aloud to somebody's face.
It helps convey some intent. Hm, that would actually be interesting. A browser plugin that automatically inserts emojis to convey your current emotions or feelings. You can set it yourself, it may learn from your interactions too.
Video can be costly, especially in countries where data is still expensive. It can be a barrier to allowing more diverse communities to also contribute unfortunately.
