Hello,
I've just written a brief essay on the relationship between reliable sources and verifiability (and, ultimately, the worth of the article.) This is my first essay, and comments and constructive criticisms are more than welcome on the essay's talk page.
The essay is entitled "No reliable sources, no verifiability, no article" and it can be found at [[WP:NRSNVNA]].
