You're quite right. I think people who work in the media (as I have done myself, here and there) sometimes assume that it is some kind of honour for a "regular person" to be called and interviewed when in fact, it can be an imposition. It is certainly not unreasonable to expect thanks when your time helps someone else hit their deadline and get paid.

This is a very interesting blog you have here, by the way. I found it quite by accident yesterday while googling for information about Learning Management Systems; it's always a pleasure to find good blogs so close to home (I am in Saint John). Keep up the good work!
