I've been looking at some video clips on YouTube of President Obama - then candidate Obama - going through Iowa making promises. The gap between his promises and his performance is the largest I've seen, well, since the Kardashian wedding and the promise of 'til death do we part.

On my YouTube channel, I put up 3-4 videos a week, and I spend a lot of money to maintain that content. When I travel, I travel with a videographer and a photographer no matter what.

I have always wanted to learn the piano, but because I travel so much, I can never get any consistency of lessons. So everywhere I go, if I can find a piano, even if it is in the lobby of a hotel or something, I go on YouTube and pick some songs to learn.

In preparing for my recording audition, my mom told me to YouTube the old 'Peanuts' Thanksgiving and Christmas specials to hear how Charlie Brown speaks. So I listened to as much as I could find online to get the voice right. Winning the role took a lot of hard work, but good fortune as well.

Thank God for YouTube. Every Thanksgiving, I'm bombarded with 'Turkey Lurkey Time.'

It makes me feel so amazing to know there's people out here that support me and follow me on Twitter and watch my shows on YouTube and come to my concert, so I'm very thankful.

YouTube and other sites will bring together all the diverse media which matters to you, from videos of family and friends to news, music, sports, cooking and much, much more.

The second you become an actress, people take the licence to make many assumptions about you. You're in trouble if you interact with a director/actor. You're in even more trouble if you don't. When I started out, a single YouTube comment would make me sad for days, and I'd wonder how people could say such nasty things about me.

I love doing YouTube. That's where my heart is, and so it makes me sad when I can't put a good, fun, energetic video out, because that's what I love to do - and that's my passion. And that's who I am.

As soon as I starting making YouTube videos, I received so much positive feedback from the online community and a demand for more content. As time went on, my filming schedule became more consistent, and it made sense to hire some help and upgrade my equipment.

I think when YouTube first came out, everyone was thinking people were just going to watch five-minute shows from now on and that people didn't have the patience anymore to watch longer programmes. But instead, everyone is binge watching and consuming ten-hour programmes and box sets of shows, so it is really interesting.

Distribution has really changed. You can make a record with a laptop in the morning and have it up on YouTube in the afternoon and be a star overnight. The talent on YouTube is incredible, and it can spread like wildfire. The downside is that it's very hard to convince the younger generation that they should pay for music.

Are companies like YouTube, Facebook, and Twitter open technology platforms or publishers with curated content? For years, Big Tech giants have tried to have it both ways, exploiting special legal protections to enrich themselves while behaving like publishers without the liabilities.

There is a saying that if you get something for free, you should know that you're the product. It was never more true than in the case of Facebook and Gmail and YouTube. You get free social-media services, and you get free funny cat videos. In exchange, you give up the most valuable asset you have, which is your personal data.

I carry with me from my male upbringing a sense that femininity is forbidden. So when I appear on YouTube with forty butterflies glued to my body and glitter all over my face, I have a sense that I'm getting away with something I'm not supposed to. I'm being decadent. I'm enjoying a forbidden pleasure. And that's fun, and it's funny.

I make a point to tweet out really funny comments I get on YouTube videos. I have the most ridiculous ones.

I'm so fascinated by YouTube culture. I have no idea how it's working, but more and more people are becoming Internet famous, and it is because it allows you to have an atmosphere in which you feel comfortable to be yourself, which you might not get otherwise.

There is nothing like a live performance. You can look at things on television, and you can look at things on YouTube, but when you get in a room full of people and you say one joke, and everyone's laughing at the same thing, it's a really great experience.

I was watching 'Deal or No Deal' on YouTube recently, and I bawled when the contestant won £250,000. I think I just like watching people achieve their dreams.

Video games and YouTube.com are creatively booming, even though Web design, as demonstrated by the ugly clutter of most major news sites, is in the pits.

The best companies in the world have all had predecessors. 'YouTube' was a dating site. You always have to evolve into something else.

What's cool about YouTube, unlike TV, is that there isn't that competition element. I mean, you could make it into that, as there's obviously numbers involved, but people are free to watch whoever they want.

The thing about stand-up was, I was doing all this sketch and YouTube stuff where I was not being censored and I got to do my own thing, and it was really cool.

Google has placed its faith in data, while Apple worships the power of design. This dichotomy made the two companies complementary. Apple would ship the phones and computers, while Google would provide Maps, Search, YouTube, and other web tools that made the devices more useful.
