Here's a must-read article for introverts. It's called How to Network: 12 Tips for Shy People, and it was written by Meridith Levinson for CIO. I especially like the part about not apologizing for being awkward or for asking people for help. Introverts tend to apologize a lot, and it's refreshing to know that some things are just OK.
