This seems like a place to ask this

What's a good platform for hosting long-ish text posts, to make them as accessible and shareable as possible? Like, I could do it on a Facebook page, but is that a good idea anymore? (If it ever was)

It's a light-hearted pop-culture thing, but seems to have generated a lot of interest already.
It's been about a decade since I was last in the blogosphere regularly, I've no idea what's 'in' any more.

Answers on a postcard.
