Chip, thanks for the mention. Actually, it was more than a mention!

One thing I should add is that going around telling people you're an expert is likely to meet with poor results. A kick in the teeth, even. It's one thing to position yourself as an expert and achieve expert status - but quite another to run around proclaiming that you're an expert when no one wants to pay attention. In fact, I think perhaps I should give that subject its own post.
