I see what you did there.

Damn, screwed twice by the same Ape...
In the modern world, I'm not sure a blog without advertising is going to work - especially hosted on your own domain.
You will have better luck with substack or koffi, who's search algorithms will at least suggest related sites - and increase your visibility.
For decent views you are going to need a way of generating audience - that used to be Facebook and Twitter, but Twitter is dead, and Facebook is showing reduced returns of a saturated market. However, reduced is but 0, so it's still worth throwing up a page.
After that, a public Mastodon profile will help in audience creation, but that's very much a slow burn, and you'll have to make sure you #tag properly.
The last time I saw this was on a slow-failing HDD.
Check a quick fsck might get you a few answers. You can find more info in the Linux manual. It could just be one or two bad blocks that you can recover and fix the problem (though, ofc, it's time to backup your data).
The other, slightly unusual time I've seen it is with mixed RAM. 16gb made of 2x6g and then 2x4gb did some real odd things to the system. If it's not the disk, and your box will boot with one stick of ram, try it to see if it fixes the issue. It could be that your RAM speeds are off (or your like me and just put two sticks you had lying around, and it basically worked until it didn't).
An outlier, that I've not seen on modern machines is io/wait for a CD-ROM to spin up, even if your not accessing the CD-ROM. Normally caused by bad cabling. Based on the age of your machine, this is unlikely, but it might be worth unplugging devices to see if one is bad and not reporting properly.
This is, if course, assuming dmsg is empty
Final thought: see if your running SELinux. If you are, turn it off and try again. Those policies are complex, and something installed in a non-standard place could be causing SELinux to slow IO as it fills your logs with warnings.
Hope that helps,
Choose an unclear gender (other, agender, etc) and your data becomes less useful. Marketing campaigns are based on broad categories, like male or female, so choosing neither lowers your data's value.
Similarly, lie about your education and your employment. Pick a made up job, be a wizard, or a spaceman. Jobs, again, are wide categories, so nonsense jobs, the more niche the better, the less they have to market things to you.
In theory you can do the same with hobbies, but three points of data, even made up data, is sellable somewhere.
Lie, of course, if you can. I'm sure there are more denizens of Hell on Facebook than the real place.
Where possible, choose other.
