I love the "Clicking "Tweet" or any status update button isn't the end; it's the beginning." comment. It encapsulates the idea that social media and doing it well is not about the post but what happens around the post. What did you read, do or see to inspire your post, did you give credit if credit was due, did you add your opinion, when someone adds their thoughts do you engage them in coversation, did you pose questions for discussion? That's where the connections are made - not in the post but in the conversation around the posts.
