Wiki, blogs, weak ties and what you need to know right now
Clueless marketers are feeling a little of the "blog buzz" (maybe because some folks think that's how Howard Dean got 10,000 people to a rally last night). They want to know how to use the medium to sell more stuff.
I don't think that's the right approach.
Joi Ito pointed me to Epeus' epigone - Kevin Marks weblog. I commend you to read it, then, if you don't understand everything he's going on about, take a few minutes to look up the missing pieces on Google.
It's a pretty subtle thing that's going on here, but it is very much going on.
