Small changes I check before posting on X

Before a post goes out on X, I run through a short list. Does the first line make sense on its own if nobody expands the post? Is there a link in the main post that would be better placed in a reply? Is there a question someone could answer in one line?

None of this guarantees reach. It does stop me from posting something that only makes sense to me.

More detail on what affects how far an X post travels.
