1. Include others in your play circle. On Twitter, avoid carrying on a lengthy conversation with someone without at least letting your other followers know the topic. It's the equivalent of a kid leaning and whispering a secret in another kid's ear. We feel left out! Take the longer, more personal conversations offline.

2. Don't just talk about yourself. If you just send out one-way messages (in social media land, they're called "broadcasts"), you are not having a conversation. Ask questions and pause to listen. Mr. Rogers was a master at modeling this. He was always interested in what others had to say. Be like Mr. Rogers.

3. Be helpful. Mr. Rogers showed us how to do this, too. Holding the door, picking up something someone dropped, educating us. Facebook, LinkedIn and Twitter give us opportunities every day to share our expertise and help people solve problems. Sounds like a day in the neighborhood.

4. Remember to say 'thank you.' Remember a meal with Mr. Rogers? Or a character who did him a favor? There was always a thank-you. Recognizing someone's thoughtfulness is a huge way to build relationships. On Twitter, the retweet function, or the RT, is a way to say "thank you" for a tweet that was helpful. You are thanking them by sending the tweet out to your followers, giving it more visibility.

5. Respect friends who may be different from you. We are different from each other and we are all special. Learned that from Mr. Rogers, too. Respect for other cultures, other political views. Seems like a given, but I've seen people on social media platforms creating space between them and others, instead of building bridges. It's okay to be who you are but it isn't okay to slam someone else's beliefs.
