Immediate comment privileges are really important. Lots of examples, but to give a silly one, someone pastes their clipboard without realizing it includes their API key or their email. Good Samaritans should be able to say, "Hey, I just caught something."

And, as another commenter mentions, if someone shares your work, you should be able to comment on that thread without delay.

This is the only reason I got myself a HN account: someone posted a link to a blog post of mine, and I happened to see the increased traffic on my VPS.

(And I stuck around after, a few posts are interesting enough. All the AI stuff isn't, and there is too much of that unfortunately.)

You reminded me how infuriating it was not to be able to post comments on StackOverflow. Felt like getting those few upvotes required was taking forever, and all without ability to ask for clarification.

Goodness that is rough, then they instantly own your posts where blanking edits are vandalism (obviously great for the internet, albeit at potential occasional individual cost).
