and certainly anyone who's been around a computer more than a week or two knows which direction "in" and "out" are customarily seen from.

Apparently not whoever wrote the man page that everyone copied ;-)
Interesting. I checked this on several machines. They actually say different things.Looks like the man pages are wrong, for RH7.3 at least. It says bi is 'blocks written', but an actual test like 'dd if=/dev/zero of=/tmp/test bs=1024 count=16384' on an otherwise nearly idle RH7.3 box gives:
Redhat 9- bi: Blocks sent to a block device (blocks/s). Latest Cygwin- bi: Blocks sent to a block device (blocks/s). Redhat 7.x- bi: Blocks sent to a block device (blocks/s). Redhat AS3- bi: blocks sent out to a block device (in blocks/s)
I would say that I probably agree, things should be relative to the cpu. However, it doesn't seem to be something that was universally agreed upon. Or maybe the man-pages were all wrong, and only got updated recently.

Which is in line with bo being 'blocks written'.
