... than naive posts from newbies?

Yes. Definitely. Many, many things. Like trolls, irrelevant
rubbish, incessant rain, muzak in public places, banks
alienating both borrowers and savers, 'friendly' dogs
terrorising small children on the beach, litter, vandalism, MPs
fiddling their expenses, supermarkets discontinuing your
favourite foods ........

What's wrong with being naive anyway? How else do newbies learn,
if not from more experienced posters giving them polite and
gentle guidance?
