What camera should I use for youtube?

So I was thinking about buying a new camera. And the camera I probably will buy (Nikon D7000) doesn't have a vari-angle LCD screen, but can you still do like vlogs without it or is that really hard? Should I buy Nikon D5200 instead?

The thing is, I want to do more than just vlogs so.yeah (that sounded weird, or was it just me that thought that?)

Added (1). At the moment I have a Nikon D3000, which you can't film with. That's why I'm getting a new camera.

It doesn't matter what camera you use really. It is all about content…

What kind of phone do you have if you have a. I phone they turn out really great videos or an iPod touch

Doesn't really matter as along as it has really good HD quality
