-So I'm wonder whether the last category re-org (which added [[:Category:DEC Asynchronous Serial Interfaces]] and [[:Category:DEC Synchronous Serial Interfaces]], and tagged all serial interfaces with one of them, as well as one of [[:Category:QBUS Serial Interfaces]], [[:Category:UNIBUS Serial Interfaces]], etc, was really the right way to go.
+So I'm wonder whether the last category re-org (which added [[:Category:DEC Asynchronous Serial Interfaces]] and [[:Category:DEC Synchronous Serial Interfaces]], and tagged all serial interfaces with one of them, as well as one of [[:Category:QBUS Serial Interfaces]], [[:Category:UNIBUS Serial Interfaces]], etc) was really the right way to go.
 The issue for me is not so much that all serial interface article have to have two tags, as simply that this serial interface category structure just isn't good for finding ''some'' 'natural groups' of serial interfaces. Finding relevant articles is the ''whole point'' of the category system - but the current serial interface category structure just isn't very good for finding, say, 'QBUS synchronous interfaces'.
 So I'm thinking of setting up 4 new categories ('QBUS synchronous interfaces', etc), and moving all the articles into them. Those 4 categories can then each be included in the two appropriate super-categories ('QBUS' and 'synchronous', for that one). Comments?
