Darren:
as with anything from the internet, make sure you take things with a grain
of sault.  Just because the guy has a call sign and writes something
coherent, doesn't mean he's automatically correct or even close to the mark.
Many licensed hams who write articles and blogs and tid bits are correct,
but things like this just have to be taken with a huge pinch of sault.
Same goes for the sub group of would be, old time HF operators who haven't
touched it in years because "the conditions aren't there" or the
"propigation is terrible" or whatever...in their experience perhaps, but the
facts of the matter are quite the opposite for those of us who actually make
an effort to closely monitor such things on a daily basses.
I get pretty choked at some local hams who would have everyone, including
new hams, believe that there is no point to getting on the HF frequencies
because propigation is so bad anyway, why bother.  These guys haven't turned
a radio with a decent antenna on in 15 years or more in most cases...or
they're of the type that sit down on 3700 and don't move.  Unless they hear
Europe blasting in at 40 over S9 on 80 meters, then they figure there's no
conditions.

anyway sorry for the rant, but I don't like intentional misinformation
especially for newer hams.
I am occasionally wrong about something and am corrected usually lol. 
However, if I am wrong, it is not intentionally misleading.
