I have to agree with Tim Bray, Scoble's post on how to be persuasive in the information age is the best he has written so far.  Not surprisingly, it points directly at the power of blogging as a tool of persuason.

I wonder if the word persuation is derived from pursue?  If so, then Scoble is saying that being persuasive doesn't mean giving a chase, but to be a person whose words are worthy of pursuit by the listener.
