they are often not very consice language, but on the other hand I do find them useful as long as they are correct and save me time sifting through docs. its all about saving time, tutorials in my mind are for when you want to 'whip something up quickly' in which case reading 20 papers and 5k documentation seems a bit of a waste. tutorials can condense enough to get u going before u do that duty. i dont mind reading a few weird sentences or fluffwords if its still magnetudes less than the full thing.
it also depends on the prompting, which true to your comment could likely use some finetuning to get it more 'readable' (its a difficult word initself being subjective. like 'clean')
