Might we add double, or triple posting to the list,
It is good to know the rules, but also great to know when to break them.
Punctuation can be used to make a sentence deliberately vague which on occasion is quite useful in a story.
Spelling can and should be twisted out of shape when a character speaks in a regional dialect.
Have to agree with re-reading though I constantly pick out new mistakes but usually not until the story is posted.
Good points though for the writin public
