Mark Zuckerberg made a big point today at f8 to point out that this year's conference isn't about any big, major product announcements as others have been in the past. This time, it was all about a bunch of smaller announcements, all aimed specifically at mobile developers.
The keynote was split into three major points of interest: Build, Grow, and Monetize. The "Build" part was about things like Anonymous login, App Links, and Parse. The "Monetize" part was about the Audience Network.
The "Grow" part included an announcement of a mobile Like button for apps. This is a Like button to let people like your in-app content with a single tap. It's available for iOS at first, and will be launched for Android "soon".
Also in the Grow segment: message dialog for iOS/Android, Send to Mobile with Facebook Login, Share Dialog for the web, mobile app ads enhancements, App Insights updates, an App Center redesign, and better requests.
