Scoble draws the wrong conclusion:

It reminded me of the time when I worked the counter at LZ Premiums in San Jose. A guy came in with ratty jeans and a T-shirt. I treated him the same way I treated all the suits that came in. He noted that and bought a nice camera system. Later, after he kept coming back in and buying a lot of stuff, I learned he was worth hundreds of millions of dollars. Said that I was the first sales guy who treated him well, which is why he brought his business back to me.

Last night I saw it again. I wore my standard jeans and T-shirt to a press meeting hosted by Become.com (a cool shopping search engine, they released a research report that found that people liked their shopping search engine better than Google). Everyone else was dressed up.

It's not a "statement" to go to a nice place dressed down. I used to think so, when I was in my teens and 20s, but I grew up. I don't much care for suits and ties, so I try to avoid going to places where they'll be required - but I wear them when they are expected. Thinking it's somehow "speaking truth to power" to dress down when a suit is expected is just childish.

Now, I'm hardly perfect on that score, but in my case, it's due to a different personality flaw: I just don't pay enough attention. More than once, I've had to buy a tie after arriving somewhere by plane :)
