Ah, from what I can see, OSR is on its way up, but still mid-ranks.
(Some years back, it was low-end -- unreviewed.)

I might do this at some point, but don't want to do it twice.  If Patashnik
hasn't released a new BibTeX by this time next year, I will probably go
with "misc".

I do agree that LWN deserves more respect, but on the other hand, RTFP.txt
has been using "unpublished" since January 2008, so I am willing to hold
off another year.  ;-)
