Facebook may seem too public at times, but according to creator Mark Zuckerberg, the social network is intended to be a place where people can share ideas and choose exactly how many people to share them with.

The 29-year-old Facebook CEO and co-founder chatted with Stanford President John Hennessy at the school on Wednesday, TechCrunch reported.

Zuckerberg said Facebook was intended to provide a communication infrastructure to let people share ideas privately.

 "A lot of times you're not comfortable communicating it publicly and maybe it's just not worth communicating it to a small set or that's not the full potential of what you want to communicate so you just don't do it, it just gets lost," he said of the pre-Facebook era.

"And that potential idea that could have been shared, or thought, or human connection and kind of option to have more connection and do more on that over time is lost.

"So I actually think kind of the fundamental innovation that Facebook brought was creating this space."

The world's second-youngest billionaire also talked about Snapchat, the ephemeral messaging service that has risen in popularity among teens and tweens. The Los Angeles startup reportedly turned down a $3 billion offer from Facebook in November, something Zuckerberg and company have never confirmed.

Zuckerberg seemed to see Facebook's innovation in Snapchat, according to TechCrunch. Like Facebook, Snapchat created an infrastructure for people to share information with varying levels of privacy.

"I think Snapchat is a super interesting privacy phenomenon because it creates a new kind of space to communicate which makes it so that things that people previously would not have been able to share, you now feel like you have place to do so," Zuckerberg told Hennessy during Wednesday's talk.

"And I think that's really important and that's a big kind of innovation that we're going to keep pushing on and keep trying to do more on and I think a lot of other companies will, too."

In other Snapchat news, Kentucky Sen. Rand Paul joined the messaging service on Wednesday as a way to engage Americans and give a glimpse into his travels, The Huffington Post reported.
