Wordpress expects every post to have at least one category. If you just roll with the vanilla setup then Wordpress will call your default category “Uncategorized.” To me, this suggests a lack of rigor; a lapse in attention to detail; a sense of “who cares?”
Well, I care.
Some posts are going to be just for fun. Slices of life. Miscellaneous. So I’m taking Austin Kleon’s cue and have renamed “Uncategorized” to “Miscellany.”
