Mark Zuckerberg, 24, set up Facebook with three friends
The man who runs Facebook has been talking to Newsbeat about the site's controversial redesign. More than a million people have signed an online petition complaining about the new look. 24-year-old Mark Zuckerberg insists the changes are for the best but says he's not ruling out a few tweaks to improve it.
Paul from Birmingham asked: "Facebook's really popular at the moment but can you really keep the popularity going for the next five years?"
Mark Zuckerberg said: "What we're trying to do with Facebook is just help people share information and connect with the people they care about, whether it's friends, family or co-workers. We think that everyone likes to communicate and share with the people around them.
So that's something that if we could help people do better, is something that people can do more and more of. Over the four years that we've been running Facebook we've found that people have been sharing more and more information. There are interesting trends on how that's happening. More of it is becoming mobile. More of it is happening all over the world. It's definitely something we see continuing.
Newsbeat's technology reporter Jim Reed asked: "How do you see the site changing in five years time? If you're a Facebook user, what can you expect in 2013 or is that just impossible to say?
"When we first got started the site had very few ways for people to share information. You could make a page and people could look you up and connect with you. Now people can share photos, they can share videos, write blog posts, write status messages and messages to each other. What we've found is people are sharing more and more information continually.
What I'd expect is that going forward, people will continue sharing more and more information and more people will be doing it, people of all ages, people in all countries all over the world. A big thing that's happened in 2008 so far is that it's gone extremely international. Now we have more than 100 million users across the world. A lot of those are in all different countries, not the least of which is the UK. More than 30% of the online population here is on Facebook, which is really exciting for us.
Facebook addict Claire from Middlesex said: "I'm very upset with the redesign and it's stopping me using the site."
"The point of the new redesign was to make it so that the most recent information and interesting information that was being shared got surfaced. We found that people were sharing so many different things that we wanted to reorganise the way that it was displayed so that the recent and interesting things showed up at the top.
So instead of a lot of different boxes all over the place from different applications that you've installed, you now have one stream on your profile of all the interesting stuff that you've been doing recently.
What we've found is that a lot of people have given us good feedback on the design, some people have given us negative feedback, but what we've found is that the stats show that people are sharing more information, sharing more photos, sharing more messages, things like that. We're pretty psyched about it."
Newsbeat's technology reporter Jim Reed said: "We've got pages and pages of texts at Radio 1. Sam says it's harder to use, Tom says it's too slow at the moment. There does seem to be a lot of Facebook users unhappy at this new look."
"There are always things that we can improve and we're looking at doing those. We really appreciate all the feedback that we're getting from people. A lot of it is really good and things that we're going to take into account and either fix or work on going forward. We're not saying that it's perfect by any means but we do think it's a good step in the right direction."
Mark Zuckerberg is estimated to be worth $1.5bn (£882m)
Dave from Guildford asked: "I'm two days younger than you. When did you first realise Facebook was going to take off as a business?"
It's kind of a funny story. I started in my dorm room at Harvard. I started it because I wanted to help people around me at Harvard share more information and wanted people to be able to get a better sense of what was going on with the people around them. It just sort of took off. We started launching and spreading it to other colleges and then we found that people at all these different schools and people of all different ages were using it.
So, we moved out to Palo Alto in California to start working on it. There was never this one period where we knew it was going to take off. We just took a term off from school to work on it and then took another term off. By the time it had about 10 million people on it and people all over the world, we were like, 'Alright. I guess we're not going to go back to school. We're going to keep on working on this'. There was never a single moment but it worked like that. It just kept on spreading. It's pretty exciting for us."
