Well, okay, here we get into it. Maybe this is fun for people to discuss. Maybe not. I am open to being swayed.

I have read enough books to tell the difference between a conversational or "dialogue" style and a formal narrative style.
I was also raised, perhaps, in a different time, under different "rules" evolved out of Internet parlance. As a result, I don't find it very disturbing to like, occasionally see a, y'know, expressiveness in or out of commas.
I think the "WRONG" you mention above could definitely be wrong in certain contexts, or it could be right in "break out" comments that add a punchline to some text. I think the "RIGHT" you have there is a bit stiff for those particular comments. They are exclamations.
Not to mention that English professors, if you ask enough of them, will tell you wildly conflicting ideas of acceptable or unacceptable usage! I think we are just going a bit with the idea that if the style is self-consistent, it indicates more care and less jumble. Uh, look, we all fuck up though, once in a while. Telling someone
how to laugh in text form is a very confusing subject.
hahahaha, whew! seems fine to me. So does a laugh leading into text, if indeed that person is someone who would do that in conversation or use laughter spontaneously in such a fashion.
It would be bizarre and confusing if someone wrote so conversationally here that they typed:
Huahahahaaaoooohhhh man, what a maroo-hoo-hoo-hoooon, he-he-he thinks we went to thah haha-ha mooon!
But distinguishing a "hahaha" or a "Ha!" doesn't seem, by comparison, to be onomatopoeia. It is more like an expression of some kind. A weird (perhaps post-post-post-modern?) one but not terribly out of place.
