YouTube is my first love.

I was too shy to do any vocal lessons or go to choirs; I just didn't want to be seen doing it. It's something that I kept to myself. I started easing into it, and I started doing talent shows, and YouTube really helped with that, too.

I never thought I'd have a career because of YouTube.

I don't really have time to watch too much, but I like 'Family Guy' and 'Entourage.' I'm also obsessed with the YouTube series 'Balls of Steel.' It's hilarious.

YouTube is covered in comments that would be better expressed - and better spelled - via a simple thumbs-up or down.

I was on Tumblr when I was 12 or 13. I was on YouTube, too. I had a channel and made music videos. It had 50,000 subscribers.

I wanted to be a venture capitalist and join Sequoia Capital. They've financed and helped built some really special and enormously successful companies, including Google, Yahoo, Paypal, YouTube, Cisco, Oracle, Apple, and also Zappos.

YouTube clips get millions, billions of hits. Reality TV programs have their own channels. How can movies attempt to compete with these kinds of numbers? And do we even need to? Are we scaring ourselves by unnecessary comparisons, by not comparing apples with apples?

Stand-ups are always good to see on YouTube. There's a guy named Mike Head who lives in Cleveland. He's great. He's an African-American stand-up.
