I found this burried in my phone and realized there was some good content here. Duh, its Seth! (No, unfortunetaly we arent on a first name basis). A few months back I saw him in person when he visited Chicago and felt these were the biggest marketing lessons:

• 37signals: wrote a computer language and gave it away for free. Hence, rails. That gave the 37signals folks legitamcy.
• Not how do I get people to fan us but ask what they want from us?
• Revolutions change things. We are living in a revolution but we are talking about stuff like Twitters re-design...(stupid!)
•  What's next? Not just 3-6 days or months. But what about 2 years from now...how many of the plans we are making are two years and not just short term. Don't only do short terms stuff!
• If it's easy, it's scarce and people are not going to talk about it because it's not remarkable. 
• Willingness to have people laugh at you and take risks, that's hard!
• People that are building things that matter, are ignoring the gatekeeper. They're just doing it.
• Ideas that spread, win. And how will we make it easy to spread? Don't yell, but make something worth talking about!

I was in Espresso Royale in East Lansing last night and saw this tip jar. Usually, as most of my friends will tell you...I'm stingy. But, this made me laugh so I tipped. (I usually do tip where appropriate by the way...I'm not THAT frugal).
