“Greed is quite a popular sin. Twitter by default is a self-centered tool. It’s about us. But it’s 100 times better if used as a conversational tool versus a dictation. I see people using Twitter as a glorified RSS feed for their blog or an ad-puker. So absent of personality, I wonder why they even try. Yes, they are in business, but if they believe that business is built on relationships, they need to make building them their business.”
