  Well, it did come out to be much "snottier" than I had intended; I 
honestly meant no insult.  I've just spent a large amount of effort 
cleaning up a big mess made by a predecessor in a contract job, and 
perhaps I'm oversensitive to that particular habit.  But you have to 
admit, it's quite pervasive now.

  That said, I've done a fair bit of poking around in the internals of 
PCB (looking into writing an HPGL output driver, a few other things) 
and I've been impressed with the design.

  I guess what I have an issue with is someone saying something like 
what you said on a publicly archived mailing list.  A lot of newbies 
are likely going to stumble across stuff like that, take it completely 
out of context, and think "ahh, this is how the real world does it" and 
adopt that philosophy for themselves.

  Get what I mean?
