I’ll be curious to hear if there is a business strategy update, but I don’t think we’ll have more insights on what “unbundling the big blue app” really means. I think one possible option is that social data and contextual identity will be the layer on top of Facebook’s new social conglomerate.
I personally will be looking more specifically for an update on mobile app installs. There's no doubt that Facebook has disrupted the app marketing space by becoming a key player in app discovery — which is the key driver behind its mobile ad revenues.
A growing and significant part of this business comes from direct marketers looking to drive app installs, primarily from gaming and other businesses that are increasingly dependent on mobile, such as travel and retail companies. These players know the lifetime value of their apps and have calculated how much they can spend to drive each app download and still have a positive return on investment (ROI). But marketers in more-traditional businesses or who are pursuing other marketing goals should pay close attention to the unique attributes of their mobile social users and optimize their social strategies to engage them.
