I didn't get an LLM vibe at all. Looking for it specifically, the bullet point about UI improvements is a candidate; the sentence following "mediawiki" could be an autocompletion; maybe the first sentence of the download section... but they're also all plausibly just a bit 'marketing team worded', so not necessarily LLM-sounding. And even if an LLM made suggestions to some small parts like these, who cares? There aren't any slop sections that waste your time, this is just like using a thesaurus — if these parts were LLM suggestions in the first place, which I don't actually expect because then there should be more of it
This type of post very poorly lends itself for auto-writing anyway. It'll put emphasis on the wrong aspects and not come out as intended, at least in my experience it's more work coaxing it to good results. It can be helpful not to start from a blank page but that's about it, I rarely find a sentence among the output that's fully usable as-is
