Lol same. I think it’s probably because commenting is more like normal conversation; you’re responding to other people in ways that are specifically meaningful to the circumstances. Writing is sorta like talking to the void in my mind. I find I spend much more time thinking and checking and re-reading to make sure I’m appealing to my imagined audience, rather than just contributing a sentence or two to a conversation where the audience is a bit more concrete.
This is a good video about who shouldn’t be sharing pictures of their keys online: https://youtu.be/6mr-7hjItX0?si=zx8QnEX1P_QpTN8U. If you’re a nobody who doesn’t share pictures of their home you will probably be ok.
