I am not the one with an issue with the acronym. I am just a nobody trying to be polite to the person who made the comment, especially since I am really not in a position to fix their problem. It feels really weird to have something as call-out-y as "excuses but no solutions" said to me as if I'm personally responsible for the concept of Personal Knowledge Management. I like it and I post stuff about it on the Fediverse. I'm not some big authority about it.

And finally, my biggest reason not to is that I don't personally believe the acronym needs to change, so I'm not going to begin to make an effort to get it done. I don't have any investment in accomplishing that change. The commenter who pointed it out is welcome to take steps towards making it happen. I said what I said because I thought that would be a better and friendlier reply than a politer version of "lol idc about this", while still being my honest thoughts on the matter.

They can't magically change the acronym people use.
