How to Deal with Social Media Conflicts

I came across this post on Mashable today that discusses how to handle disagreements and criticism one might encounter on Facebook, twitter, or even a blog. The article highlights 3 perspectives to remember when you respond to these comments. Here they are:
1. Don't take it personally
Most negative comments are about what you wrote, and not you. So don't take it too personally, they just don't agree with what you wrote.
2. Process before responding
Think about what you write before responding back. Sure you might be tempted to write a quick rebuttal but it is important to understand the other person's opinion as well.
3. Find something to agree with
Finding a common ground (even if its small) to agree on can break the ice in many occasions.
Do you have any more tips on dealing with social media conflict?
