If you're a social media practitioner or just really interested, here's a quick tip for a must have.

1. Go to Google Alerts
2. Login to your Google account if you haven't already
3. Create an alert for "social media" (include the quotes)
4. Type: Change to News
5. How often: Once a day

Now you have a daily update on the state of the social media industry. The term "social media" has become enough of a buzz word to be used as a keyword filter. I don't recommend getting alerts from blogs or other UGC sources because there's too much noise. The News media acts as a great secondary filter.
