Phal. spikes. To cut or not to cut?

[FranningtonBear]

Like, I imagine most of us, my introduction to orchids came by way of a supermarket NOID Phalaenopsis that I managed to keep alive more by luck than correct care.

Since my collection has grown and my Phals have survived and re-bloomed without issue, I have neglected to really finely hone my care of them. I have always cut a flower spike back, as close to the base as I can manage once all the flowers have gone over. Now by the somewhat confusing powers of the internet, I see some people advocate doing what I have been doing, some advise cutting it higher up and some say not to interfere at all.

What is the general consensus here?
