At its F8 developer's conference on Wednesday, Facebook CEO Mark Zuckerberg unveiled new products and policies geared towards making the world's largest social media site feel less intrusive, as well as making it more inclusive to mobile developers (but also more exclusive to unaffiliated ad networks). The changes are part of Zuckerberg's efforts to shift the company towards a more "mature" outlook and attitude.

There were several changes and products announced at Facebook's F8, but the broadest development discussed was a change in motto for the company. Zuckerberg told the audience in his keynote that Facebook's old motto of "Move Fast and Break Things" will be left behind, according to Mashable. He joked that the new motto was "Move Fast With Stable Infra," but the point was made: Facebook is no longer an upstart social media firm. It's established. It's big. And it doesn't need to be a disrupter in the industry it clearly leads. But the company doesn't want to reach a point of stasis, either.

Part of the change in motto encourages better service from a technical standpoint. Zuckerberg promised that bugs in Facebook's website or apps will be fixed within two days.

Facebook: Connectivity, "Anonymity" and Data Consolidation

The bigger changes to the maturing social networking company affect its users directly. Facebook will be rolling out new permissions for apps and other products, and privacy is a point of emphasis. For example, while a public profile is always required on Facebook, users will have options to make more information private, such as birth dates, friends lists and other personal data.

The final piece of Facebook's readjustment puzzle is Facebook's new mobile ad targeting system called Audience Network. As we previously reported, the mobile ad network profiles mobile users and provides behavioral and personal data for marketers to target users more effectively.

All put together, this is a major redesign of Facebook's behind-the-scenes nuts and bolts, simultaneously making the network more attractive to privacy-conscious new users, launching an in-house mobile ad network, and consolidating (at the user's opt-in choice) all ad targeting data only under Facebook's roof.

With these major changes, Facebook reinforces its mobile, multi-app push, and reminds us that the company isn't solely interested in buying futuristic technology -- it's also paying attention to the current state of social media.
