Twitter allows you to interact anyone in the world (that is on Twitter, of course). I'm going to NYC for the first time this week. I want to eat at places where the locals eat, not what's trendy on the Web or TV. How did I get recommendations? Twitter. I reached out to NY food bloggers and they happily responded with tips. I don't need to get introduced by someone else. I don't need to personally know them or "friend them". I don't need to pay for 3rd party services to hunt down a phone number or an email address. People often miss on what I think is one of the most fantastic features of Twitter.
