Facebook held a developer's garage event at their headquarters in Palo Alto. Mark Zuckerberg took the stage to talk a bit about the history of Facebook. He focused on Facebook Photos as being a key catalyst that led to everything the social network is today. He noted that when they launched the product, they didn't have all of the features that their competitors did. For e.g., they didn't have high-resolution photos and you couldn't print them. But one thing they did have was the social element — and this changed everything.
"Those features by themselves were more important than anything else combined," Zuckerberg said of the social elements of Facebook Photos. He then said "The photo product that we've is maybe five or six times more used than every other product on the web — combined," Zuckerberg stated. (emphasis added)
