I'm interested in hearing how Facebook plans to protect children (13-18 year old) with the new video chat feature. I'm sure there's a plan, and there already are plans in place with their existing products, but I would be interested in hearing Mark's thoughts on children and this new video feature, and whether or not there would be any parental controls. I know Facebook disables certain features for users under 16, so I'm wondering if they would disable video chat for younger users too.

I really wish someone in the media panel would ask this question.

Just had my first facebook chat; setting aside all the hoopla and google+ hangout comparisons, I was reminded that it is VERY nice to talk to a friend face-to-face.

It's a small pleasure in a world full of being long distances from friends and loved ones. So, I'm excited, personally. It felt great, and had relatively few hiccups for a launch-day service.

No doubt it's very nice that it's integrated. But GMail has had 1 on 1 video chat for years(s?) now.

I think Facebook built up expectations way too high by claiming what they were launching was awesome. Everyone was expecting them to come out blazing with a launch that would put the Google+ challenge to rest.

Nice work Facebook. Hangout is nice, but 700M with video chat -- today. That's pretty huge.

And the question about Skype cannibailizing their Skype user base misses that Skype is now owned by MS. They don't care about Skype revenue. They want adoption.

Opened it up for questions. First question: Will you do group video chat? What do you think of Google+ Hangouts?

That has to hurt...

I missed the start of the Q&A -- would you mind summarizing the response?

In response to that question: Zuckerberg: "We started working on this before Bates was at Skype, then closer once he got there, and now they’re at Microsoft which Facebook has a long-standing relationship with. So there’s going to be a lot more. But one-to-one is the most important video experience, Bates and Zuckerberg say.

"I’m not going to say a lot about Google+. We’ve all only had a little time to use it. Like I said, the last five years have been about connecting people, now about apps. I think you’ll see a lot of companies and apps building social stuff. I see this as validation of the way the next five years are going to play out. We’re sure it’s going to happen, and if we don’t someone else will do it."

The only interesting part was Mark's subtle shots at Google for "trying to do everything" as opposed to Facebook's individual developer/partnership model. Google's trying to do everything model is really a partnership via acquisition model. And regardless, all the aqui-partners like YouTube and Android are now market leaders. So doing everything in this case, seems to work well.

its only a matter of time before google lets developers tie in.

They do... Chrome Web Apps, extensions, android apps. I can see the Web Apps/Games incorporating nicely with Google+.

i mean tie into google+ specifically.

It looks like it's coming:

On a side note, below the video was an error box because a misconfiguration of the live stream box.

It says a lot about the current status of developing on the fb platform.

Facebook video chat doesn't support Opera 11.50. Really, Facebook?
