Like I said, the wording may not be entirely clear; but the point is, was, and always has been, to post code in CUFP. If one's intent is to discourse at some length about how/why the code was written, or whatever, then that's Meditations. If the main point is to advertise one's product (and that does seem to have been the secondary point in this particular case), then maybe Perl News is the best place.
