Agreed with Thrax and pretty much everyone else. Twitter has absolutely changed my life, professionally and personally.

Quoting drasnor

I'm still trying to figure out how to use social media. I can't talk about anything work-related and since I pretty much work 60 hrs a week that doesn't leave much else to talk about.

you know, I don't really talk about work all that much. When I'm at the studio, it's the same thing. I'm operating camera, I'm moving faders.. pretty much all there is to it.

What really propelled Twitter for me was when I started just talking about things I'm into and finding people that are into the same things. Art, 3D, VFX, animation, filmmaking, graphics... I tweet about what I've learned, or what I'm playing with on my PC, and have had great discussions and critiques with those I follow.

Twitter is about 'what are you doing'. That's pretty much the worst way to put it, in my opinion. I found it's strength to be talking to those about everything but.
