Usenet is not the only community that uses '>' for quotes. I wasn't aware that Reddit or open-source mailing lists were so unusual, but I can certainly claim no lineage with Usenet. I will, however, take that assumption as a compliment of the highest order, even if it involved no ingenuity on my part. As an aside, I'm just going to assume that this is a counterexample to the "be nice" policy that is in effect for Stack Exchange-affiliated sites? Or is this rather another "founder exception" to the rules?
