I could have expanded on the frequency and engagement point. Currently, the most representative social interactions happen off of services like FB (such as texting, phone calls, going to the movies, grabbing coffee, meeting someone, etc). FB then relies on the user to input this data with the promise that the data will be spit back out in a relevant, useful, and entertaining way. Phones, contrastingly, can pick up all this external engagement passively and produce a more representative of a true life social network. Because its data collection is passive, it can dynamically adapt a network without explicit user input.
