Social media as communication

We could not use any of the phone or texting after the earthquake yesterday.But we could use emails and the internet for social networking. I found this article By Leslie Kwoh of the The Star-Ledger that explains everything I experience.This is the new way to communicate."It’s really across every industry at this point," said Dan Rayburn, a digital media analyst with Frost & Sullivan.In the four hours after the event, Facebook saw 3 million mentions of "earthquake" in users’ status updates, spokesman Andrew Noyes said.Jodi Olson, a spokeswoman for Twitter, said within a minute of the earthquake there were more than 40,000 earthquake-related tweets.

Hello
I am new to this group and still wondering around to figure out how everything works.
Does this group do anything to promote each others businesses, like link exchanges or facebook or twitter friends/followers?
I wrote a book and have 2 websites dealing with missed opportunities and how we can learn from them to become more successful.
