I didn't see anything on Twitter as I deliberately avoid STFC stuff on Twitter for very much this reason. I was talking about the reaction on here, mainly from people claiming to be able to judge his ability/commitment/professionalism from what he'd written on Twitter.
I don't use twitter at all, apart form occasionally glancing at Spacey's stuff. I meant those of our fan base who were spitting feathers were those who generally spend a large amount of time in the twitterverse (did I really just say that?) and also post here.
