i also use a lot of hyphens and exclamation marks when appropriately used punctuation helps with reader comprehension and avoids ambiguity lots of subjectively good authors use a ton of punctuation for that reason  it may seem like an odd practice but thats partly because discourse on the internet is full of run-on sentences poor grammar and generally terrible writing if you go to a book store and read decent literature with a professional editor its chock-full of commas
