Remember, too (as I was just discussing with a Wikipedia editor
I met by chance sitting next to me on an airplane today) that
our templates which say "Warning: this article/sentence does
not adequately cite its source(s)" do *not* necessarily imply,
"so you, the editor who wrote it, had better supply some pronto,
'cause the rest of us are just itching to delete it." The more
important intent of those templates is to warn the *reader*,
and the message is simply, "so sorry, we're less sure of this fact
than we'd like to be, so please take it with as many additional
grains of salt as you deem necessary."
