Being thankful for social media

In the spirit of Thanksgiving, that quintessentially American holiday, I want to take a moment to give thanks for social media (including our own wiki). I'm starting a list of reasons to be thankful for social media, so please add to this by commenting below.

1. Social media turns monologues into dialogues
   
2. Social media empowers people with information
   
3. Social media shines the light in darkened corporate corners
4. Social media maximizes a staff's time and effort (create once, use many times)
   
5. Social media fishes where the fish are (push instead of pull)
6. Social media unleashes creativity
   
7. Social media breaks down departmental silos
8. Social media puts the 'team' back in teamwork
9. Social media is bottom up, not top down
10. Social media helps shy people find a voice
11. Social media helps us all work smarter, not harder
