As I'm working at a grown-up site that doesn't ban blogging but has a blogging policy instead, I think it's only fair that I follow it, even if I'm an external consultant and not a full-time employee. If they play fair with me, I'll play fair with them. So I've added one of those disclaimer things in the side-bar. I'm generally pretty discrete in my blogging activities anyway and I suspect that any regular reader would have guessed the position by now.
