I'll try to make this a little less funny.
I don't claim to have worked in a shop, I did. If you want proof please call Phonography in Ringwood Hampshire 01425 461230 and Phil, Drew or Paul can attest to my helping them out off and on. It was in this very shop that I met Roy Gregory and where he asked me to write some record reviews for this new magazine he was starting, the rest is history ... perhaps there will be a blue plaque there one day ;->
I also didn't claim to be able to spot a forum user. In the course of helping customers I often asked them if they used any of the fora, mainly the Naim one as Phonography was a Naim dealership, and inevitably the answer was a negative.
I don't discuss forum use as if I am not a poster, I was trying to pass on my experience with the average HiFi purchaser. I have posted to the forums for many years, been banned from one even ;->
I think they are a useful place for many, especially if you want to save some money and I tried for many years to encourage people to post and join in with their experiences.
Hope that helps clarify things
