I draft tweets, like, 20 times.

I just talk just to talk. I like to see what other people think. There's some things somebody tweets me every day where I'm like, 'Wow, I never thought of this issue that way.' It starts great conversation with people who I would never get a chance to actually communicate with.

I don't just post a video and then get offline. After uploading, I love to respond to comments, tweets, and messages about the video.

I actually quite love following Lisa Rinna on Twitter, because she tweets like I tweet, which is like, 'Just dropped off the kids!' Or, 'Hey, here's a great sale at the grocery store!' It's such real life, and to me she's like a celebrity - she looks like Hollywood to me - that following her makes me feel like, stars are just like us!

We are deluged with information. We have to process now three times as much data as we would have done 50 years ago. We're bombarded with tweets, with emails - a state of continuous disruption - and that's bad for our decision making and bad for our thinking.

The emails and the tweets and the Facebook posts and the fan mail that we get from young people all over America that are on the football team or on the hockey team are so touching. They tell me, 'Hey, this is me. I still have to remain in the closet, but your role in '90210' makes me feel better the way being gay is being portrayed.'

Social media teams tend to be decentralized - a motley mix of in-house experts, off-site consultants and international partners. The result: Confusion, rogue tweets, and off-message posts are almost inevitable. The worst gaffes live on in social media infamy.

Fans believe they have a relationship with you, either through your TV character or, more reasonably, through the tweets you may have exchanged. In a way, you have gotten to know them. You learn about people's kids, families, pets.

Most of us still haven't grasped the fact that everything we commit to the digital space - not just our public blogs and broadcast tweets, but every private text message, email, and voicemail is likely to be stored and accessible. Forever.

For comedians, we're all kind of tweeting our thoughts instead of spending time developing them. You can gauge how good a joke might be by how many times it gets retweeted, but it takes discipline to go back through the tweets and then develop jokes from them.

I'm less interested in how people are following each other and more interested in how they are following topics and tweets themselves. People are following more key words and concepts and more ideas and acting on those rather than individuals or organizations.

In America, everyone writes but no one reads. Everyone's writing all day long - sending emails, tweets, text messages; they all think they're James Cameron's Avatar, performing in some video game for which they make up the script.

Anytime people read my tweets, they hear it in Auto-Tune.

For me, Twitter works best as a way of taking pictures of being stuck in traffic on the Brooklyn Bridge. If people really want to read really funny quips about life, parenting, and pop culture, then by all means read Michael Ian Black's tweets.

I've never gone on Facebook and am not sure I understand it. The same goes for Twitter. I have someone sending tweets and pretending to be me, but I don't know why.

There's been thousands of very, very funny and also very, very nasty tweets about me.

I get occasional tweets from people asking what shampoo and conditioner I use. I go straight for the Costco brand, Kirkland brand, the bulk shampoo. That's as far as I go.

Just because someone says something, whether it's at the podium during the briefing or the president tweets, I can't always assume that's factual. That's insane. We have to be very quick on our toes in fact checking.

Governments do not care about your Facebook-assembled opinion. Incompetent politicians don't read your tweets; there are reasons for them being out of touch. Change does not come about for 'likes' on a page, though the ideas for it may start there.

If you're caught up in a massive scandal there are probably tens of thousands of tweets about you.
