I was editing a doc on our internal wiki, and I kept getting the wiki-speak header directive wrong. After a while, I figured out why I was typing .h3 instead of h3. into the editing window. I’m almost surprised I didn’t type .h 3 since that’s the proper directive in mm (the Memorandum Macros). On the other hand, it has been a few years since I even edited a man page, let alone a full document in troff.

I don’t really miss PWB/UNIX, but it was very fine for its time. Source control with SCCS, yacc/lex, troff, wow.
