I hate writing about personal stuff. I don't have a Facebook page. I don't use my Twitter account. I am familiar with both, but I don't use them.

For the most part, I don't have a Facebook page; I don't Twitter.

Facebook is quite entrenched and has a network effect. It's hard to break into a network once it's formed.

I am not a fan of Facebook or Twitter. They both allow too much information to be available and they make privacy a thing of the past.

People should pursue what they're passionate about. That will make them happier than pretty much anything else.

I think most of the important stuff on the Internet has been built. There will be continued innovation, for sure, but the great problems of the Internet have essentially been solved.
