This issue has existed since the beginning of when the CMS was written, but when a blog is initially created for the first time, any tags selected are lost. The blog needs to be edited, tags re-added, blog saved, and then they stick.
If someone forgets to do this, the tags disappear into the ether, but of course adding a warning is not the solution, fixing the issue is.
At the same time, if at least one tag is not selected when a post is first created, the page crashes, so selecting a tag is mandatory at this point even though it does nothing.
Also just noticed that for some reason, the tags don't always seem to show up when viewing either, e.g.: https://blog.interlinked.us/tag/tech
Article 73 is categorized under tech as its tag, but it doesn't show up either when filtering to that tag, or on the main blog page.
