As Lennart and others have explained, because it is customary to refer
first to more important things, and lines are more fundamental when
dealing with an Emacs buffer than columns. It is a bigger movement to
advance a line than a column. line-number-mode is enabled by default,
column-number-mode is not.

12/25 can be confused with? A rational number? :)

Use "r" (for rows) and "c". 25r32c is still horrible, though.

That is true, but it doesn't mean that going from x,y to row,column
(or column,row :) is intuitive at all.

That's true for every format described in this tread, even the "Ln vs.
Cn vs. (l,c)" style that we have now.

Same here. I won't be using it anyway.
