I've found it harder over time to keep maintaining my own site, because the engagement dropped off rapidly over a decade or so ago and I just pretty much log in to clear out spam from the moderation queue. But I keep going as much for myself (having to remember what I did on this or that project a few years ago) as for having a little repository of knowledge for people who are building stuff.
It is still very hard to beat a static text format for searchability and archiveability, IMO. Forums moving to Facebook/Reddit then Discord is making knowledge more and more ephemeral. And videos are very hard to search and hunt down the exact moment you're looking for in comparison.
So it's a continual uphill battle of blogging only for passion reasons.
