Not at all. But since you didn't make it clear that it was your work, and the work is of publishable quality, I just wanted to make sure you hadn't neglected attribution. I'm not accusing you of this, but people cut and paste things without attribution all the time, not realizing that the same courtesies to the original author/source should be adhered to even in informal settings. I'm definitely not suggesting that you need a bibliography or footnotes in this case.
Anyway, thanks for the research & excellent writing! Carry on.
