I delete the vast majority of what I type out. Mostly stuff that’s personal experience based that, while adding to the conversation, doesn’t really matter to anyone and isn’t that interesting.

I start writing it because I care enough, and stop when I realize nobody else will.

Sometimes I let myself finish fleshing out the thought, then delete it, but often I just get the bulk of my thoughts out and give up when editing it. I’m pretty verbose, and don’t really have much of an outlet in real life, and I’m an anxious mess about interactions, so… it’s just a way to relieve some of the pressure without it impacting anything.
