Exactly! That, and I can tweak my writing to see if it conveys what I want. I cannot just hit ctrl+z when I'm talking.

Most times I feel I'm having these galaxy-brain thoughts but they come across as pea-brain sentences when trying to articulate them (how long is long enough for a rant/explanation?). Going meta has also not gone well for me. By that I mean discussing about how we're discussing the topic at hand. It seems to be shrugged off as a tangent or distraction, when I believe it's a good baseline for the current and future conversations I might have with the person.

Discourse online is better suited for the exchanges I like to have with others (such as the folks on this very thread), because arguments can be better fleshed out and people are less afraid to share their rationale. Ideas and perspectives can clash, but it's not necessarily bad. Just like peer review in science papers.
