People often talk about how Twitter is great at conversation, but the majority of folks I know rarely experience it as anything other than a one way street.
But sometimes a great conversation does happen, most often spontaneously.
The attached PDF is a loose transcript of a conversation that broke loose for about a half hour involving 18 people the other night based on a simple tweet I put out asking whether David Armano's accepting a position at Edelman said anything about the struggle between ad agencies and PR agencies for control of social media. (And since there was no hashtag involved, I'm sure I missed out on several side threads that took off.)
It took on several interesting tangents, and while I know most of the participants in real life, I did get to meet some new people as a result.
Which is why Twitter proves so addictive.
