Nah. I don't know him personally, but from what I know of him - from here, Twitter and his blog - he seems a good bloke and not the sort of needy person that creates second accounts to back his opinions up.
I don't think he is. Jem is a positive fan and defender of the club's policies, but I don't think that he'd have access to transfer fees and wages to such detail.
I'm glad we didn't for whatever reason. The stadium was only ever going to be built once in our lifetimes, so I'm glad they did it properly instead of half arsed.
