Bain spent his first few months at Twitter outside the office, meeting with ad agencies and advertisers and listening to what they wanted from Twitter. He visited 140 chief marketing officers in 140 days, sometimes with Costolo in tow. (Get it? Tweets max out at 140 characters.) One of Bain’s slides showed the path not taken: a clean Twitter website under assault from banner ads hawking lotion, handbags, and cell phones, which descend onto the page amid dramatic clouds of virtual smoke.

I've met the team from Twitter a couple times and they are legit. Their product has a ways to go, but there are smart, ethical, value-focused people on the job over there.
