Facebook turns 10 years old today. I was reflecting on that milestone last night, when I sat awake in bed remembering my first moments browsing thefacebook.com back in my college dorm room. It was a totally different experience back then that was entirely limited to a batch of schools (by the time I got on) and required a .edu email address to register. I mostly used it to connect to the new friends I was meeting in classes. Today, I use it to stay in touch with old friends. Funny how things change. I'm not the only one reflecting. Facebook CEO Mark Zuckerberg recently penned a blog post discussing his own thoughts on Facebook's past, present and future.

"People often ask if I always knew that Facebook would become what it is today," he said. "No way… I always thought this was important — giving people the power to share and stay connected, empowering people to build their own communities themselves. When I reflect on the last 10 years, one question I ask myself is: why were we the ones to build this? We were just students. We had way fewer resources than big companies. If they had focused on this problem, they could have done it. The only answer I can think of is: we just cared more."

Zuckerberg says Facebook still cares more than its competitors, though it has come a long way in 10 years. It's now a publicly traded company. A huge bulk of its revenues now come from mobile devices, instead of chunky desktops inside dorm rooms. Facebook has since added ads, apps, Graph Search, Instagram, and has offices around the globe. But what's next? Zuckerberg knows he can't let Facebook sit still.

"Today, social networks are mostly about sharing moments," he said. "In the next decade, we have the opportunity to answer questions and solve complex problems… technology will enable us to create many more ways to capture and communicate new kinds of experiences." It's clear Zuckerberg sees Facebook more than just a social network used for posting pictures and sharing status updates – arguably the root of what it once was – where will it be in 10 more years? I can't wait to see.
