Psh. I think Alanis just wrote a bad song and used the meta line to excuse herself.
I think you shouldn't excuse drivel just because it works. What happened to doing things well for the sake of doing them well? Just because Seth is good at what he does, just because Scoble and Arrington are good at arousing attention, doesn't mean we should look to them for inspiration.
But he is doing things well for the sake of doing them well. He's a marketer; he markets well. Look at him as a practitioner, not a commentator, and do as he does, not as he says.
See, I don't think marketing counts as doing something unless you're doing it in tandem with a great product. Marketing is a secondary talent: if you market just to market then I consider you a waste. So it's fine when companies like Apple and Geico have excellent commercials, because their commercials do a good job of pointing out that they are the best. When you market better than you design, there's a problem.
