I watch Twitch alot when I'm working (well, technically I just listen) and it helps.
I haven't done it so much recently, I mainly watch Destiny streamers but Destiny is on it's arse at the moment waiting for D2.
I stream on Twitch when I'm playing too, not for viewers and revenue, rather so I can recorded footage of everything I did in case I did something 1,000,000 to 1 and I have the footage!
