Yep, Right-on IMHO from one old fogey usenet user to another. Most of the abbreviations started there way before the web or the internet (and “smileys” as well). Just wasn’t as well known. OBfact - most of the old usenet posts are available on Google. Look up kremvax for fun or just your own old posts.
“Just wasn’t as well known.”
Yeah, but that’s kinda the point of the current discussion. Them being well known and well used.
