Rob Pegoraro:

I first wrote this post on my public Facebook page in May of 2010 as a response to friend requests from readers, publicists and other people whom I hadn’t actually met. Since then, things have changed: Facebook’s privacy implications have gotten trickier, Plaxo and MySpace vanished from relevance, LinkedIn is more useful, a follower-etiquette question has come up on Twitter, and Google+ has brought its own social-networking issues.

Some people really stress out over whether to follow back or not. I don’t.
