So the point of my post below is now redundant after I received an email today from Jeff Jarvis of the Buzz Machine - one of the official bloggers for the '07 WEF.
'No, the WEF is doing nothing to our posts; they go up automatically after we post them on our own blogs. I don't know what happened in the past but note that your link to Ethan is from last year...'
Excellent to know from someone on the inside.
NB: do read his bio - he has phenomenal credentials.
