> We aren’t talking anecdotally about “people you know”. Agreed, I'm raising anecdotes as I haven't seen any data users frequently update. Quick search shows https://zephoria.com/top-15-valuable-facebook-statistics/ https://zephoria.com/top-15-valuable-facebook-statistics/. If you do the math, there's about 1.3 status updates/week/active-user. That's not a lot of voluntary data being given per user and I suspect this is subject to a huge power law where median is far less than 1. > how will it correlate LinkedIn profiles with Google users? Profiles are public and picked up by Google search. Correlation is pretty easy to do - simple method is real name match + geo-ip. > How many people use email in 2018 for personal communications? I don't have solid data; do you? That said, I and almost everyone I know uses email as the primary means for long-form (i.e. anything that requires more than a sentence) personal communication. (I feel like we're talking past each other due to the lack of data + being in different circles) > People only use maps when they don’t know where they are going. People will check in a lot more. Source on both pieces of data? I'm skeptical as: 1. Maps is valuable for traffic-adjusted navigation. 2. Maps has 1B montly active users 3. Check-ins are rare. (looking at my feed - I can't find numbers)
