What four lessons from 2007 will you take into 2008 about social media and nonprofits?

For my New Year's reflection, I decided to start a meme with the questions and tag some colleagues:
"What if I could start all my social media and nonprofits work over from scratch? What would I do differently? What lessons have I learned that will stick with me for 2008?"
I managed to come up with four lessons learned, but the most important was this one:
Don't Join New Social Networks Without Thinking. This is especially important if you got an email invitation from a friend. If I learned anything from the Shelfari and the Spock, it is to use your critical thinking skills before joining a social network that a trusted friend has invited you to join. Ask your friend why they invited you. Refrain from joining as a knee jerk response until you know that your friend has really checked out the service and has not been duped. (Thanks Nancy White)
