This page doesn't require an explanation.
It should, and perhaps does, go without saying. If these columns are my point of reference, my drawer, my "thinking ouloud" space, then it makes sense for me to use them as a space in which I examine why it is that I allow them (or they demand) to be a subject for a column. Admittedly there's something of a circular argument here: having chosen to make this a topic of a column, I then proceed to fill up that same column with an explanation/examination of why I made that choice. Still, this page is definitely not off topic.
