For many years, I shut it down-- changed it from Wordpress to static html and hosted on netlify. Ignored it completely for 3+ years.
Then last year, I restarted it-- moved to Ghost this time-- its a better (simpler?) version of Wordpress. Tried a dozen static generators, hated all of them, as beyond the simple "write 5 blogs and publish" they become hard to use. I like Ghost's front end, like that they take care of hosting. I've had a few articles blow up on HN/Reddit, Ghost managed the spike.
The strange thing is you can never tell which article of yours will blow up. One of mine flopped on HN, 0 upvotes. Then someone else submitted it again, this time it was front page for several hours, got 60-70k visitors in a day. also blew up on Reddit/Linkedin, had random poeple trying to friend me.
Other articles I thought would be useful and in line with what people were discussing here-- vanished without a trace. Or they got 5-10 upvotes, and then vanished (with 0 comments).
I keep the blog now because I see people still find old articles I wrote useful. There is a small expense, but tis worth it, as when I have something to say, I dont have to worry about seeing where I will share it. If nothing else, the few poeple subscribed will see it.
I no longer write to a schdule (which is what marketers advise-- write every week! promote!), as that made me hate it. Now I write what I love. Still try some promotion by sharing here /Reddit, but thats about it. Quit Twitter/FB years ago, so never go there.
So yes, I would recommend people have a blog, even if you publish once every few months. ITs nice to have a platform you control.
