I wonder, though ... it seems to me like part of the reason Bob takes so much abuse there is that, for stuff out of his control, Bob is pretty much left out there to take the hit. It's very hard for a casual blogger to tell the difference between "Bob not answering the question because he's not allowed to" and "Bob not answering the question because he's ignoring it". And so, some of the venom that ought to be more properly aimed at the agency is instead aimed at the person --- which is both unfair and unproductive.

It seems to me like TSA could make Bob's job a little easier on the blog in any number of ways, just by allowing him more resources and flexibility in how he's allowed to interact with the public on the blog.
