One is that, as far as I can see, it fails to explain *why* the
reference for 0dBu is 0.775V.  Yes, I know the answer, but it is not
clear on that page.
Also, a minor irk, is that when talking about dBm they say "Typically
the impedance (load) is 600 ohms" -- well, not in my experience in RF
where dBm is very commonly used, and impedances are typically 50 or 75
Ohms.
