Indeed.  I've had the privilege of studying the Master's works (i.e., Knuth), and this is a point he makes more than once.   I highly recommend his "Mathematical Writing".  Anybody who's going to do mathematical writing (e.g., PhD students) should read same and learn its lessons.

To me, a juxtaposition of math italics is implied multiplication, not a label.  Besides, math italics were not designed for the formation of words; something like $c_{in}$ just Looks Funny.

Somehow I got into the habit of doing that a very long time ago.  Maybe this was in Spivak's "Joy of TeX"; I don't remember.
