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/. 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)
