Facebook CEO Mark Zuckerberg is holding his first live public Q&A via Facebook's new live video streaming feature.

The event, which starts at 2:30 p.m. ET, was announced by Zuckerberg last week on his Facebook page. He invited users to post questions in the comments, and for others to vote on them by "liking" the comments.

Zuckerberg responded to a user asking about his future artificial intelligence plans, saying, "I'm looking forward to discussing this and more on Tuesday."

As of Tuesday morning, some of the most popular questions were requests for new Facebook features, such as folders to store things like recipes that have been posted on their wall, or a way to create "virtual reality" video views from multiple Facebook Live views. One user also asked Facebook to sponsor the creation of a new "energy efficient" device designed to "bring the digital age" to places like Africa, but didn't offer other details. Another asked if Zuckerberg ever thinks about how Facebook "affects the human spirit/soul when it comes to detaching from nature or a more human interaction?"

Zuckerberg said he has previously held "town hall" question and answer sessions while travelling and at Facebook headquarters, but will be able to "hear from more of our community at once" on Facebook Live.
