Why "Marginalia"?

I first read Billy Collins's "Marginalia" as part of a poetry writing course I took while living in England.  At ten stanzas in length, it is a quick read, but it has lingered on in my memory in the decade that has passed between then and now.  I am a margin scribbler (one reason I continue to resist the eReader revolution).  I am a questioner, cheerleader, and snarky critic, armed with a #2 pencil.

If I said that my scribbling was confined to the literal page, I'd be lying.  I equally question, cheer, and snark in my head as I "read" life's unfolding plot.
