Vlogging and cameras

I know several people who have tried to start video blogs (Ok...those people have been me), but there's always the problem of how to seem natural on camera. When watching vlogs of people like Philip DeFranco and the Vlog Brothers, you can see that they treat the camera just as a person that they're talking to, not like a camera. Here's a video of John Green being comfortable in front of a camera.

So for those of us that might get a little camera shy, here's an article that gives tips on becoming more comfortable. It's simple things like practicing what you're going to say (but not too much), being able to ramble, and just remembering to breathe. So maybe all of you (and me) will be able to act natural now!
