For me, this sort of thing highlights how we all interpret what we see in front of us differently - and much will depend on mood... When I saw it, I laughed, so that was my initial reaction.
However, given the amount of piss-taking on forums, in reference to 'foo' (a word I hate intensely), because unlike 'placebo effect', which is a recognised and accepted phenomenon (although not always applicable to where it is applied), it's a purely derogatory term coined by those who simply won't accept that not everything that people genuinely hear can currently be measured,
I can also understand Paul and Neil's reaction, as many folks are fed up having their valid observations rudely dismissed as 'imagined'.
However, the key question is: did Bob mean any malice by posting what he did? I sincerely suspect not, and just thought it was something funny to post, to lighten up a dull Sunday morning, which unfortunately was taken the wrong way.
Am I right, Bob?
Marco.
