The Scary Devil Monastery? A little, many years ago. Very briefly in alt.callahans (most recently in 2004 via a crosspost from several other newsgroups), I found the volume of traffic there overwhelming. And several times intermittently on alt.comp*, comp.std.c and comp.std.c++ and the like (and in all sort of odd places in alt.* and rec.* and uk.*, particularly the filk and SF fandom related ones). Almost always with keris or keristor somewhere in the email address (and if anyone is using one of those the odds are good that it's me; on LJ keris is someone else, and .org I think is a German medical organisation).

Mind you, in the heyday of Usenet I didn't do Perl, I was C/C++ only (well, plus various assemblers and odd bits of scripting in bash and awk).
