I admit to feeling let down, I'd like to know what questions he was actually given to choose from, no way was he sat there reading all of them.
We always advise webchatees to read the advance questions and when they arrive we give them a print out of questions arranged into subjects to help them negotiate the thread. JC and team had certainly read the thread before they came in, as they had a clear idea of some questions they wanted to answer.
We see our role as pointing out the issues on which there are multiple questions and keeping webchattees abreast of new questions that come in, but the truth is 25 minutes isn't long enough to cover the ground and we only realised he was only going to be here for that long half way through his visit, when his adviser told us he needed to catch a train.
At that point we urged speed and succinct answers and suggested a few key topic areas where there were multiple questions - had we had longer I'm sure he would have covered more of those topics.
