I agree, people are seeking...umm, I don't know what, and they feel they will find it through the vehicle that is social media and other people's accolades rather then the old fashioned way of seeking and finding within oneself. So, more and more information gets shared and more collected. You mention LinkedIn. I remember the good old days when it used to be about business and now...it's gone full-nutbag...and not in a really great way I like have.
I don't have time for YouTube mostly, but I know the type of thing you're referring to and have my own sources for it. As I mentioned in another comment and the post itself, we're all tracked and collated even if we don't go on the interwebs, just having employment, going to school, hospital, getting a passport, drivers licence or credit is enough. Once the floodgates open it's too late.
Anyway, I'll be dead and forgotten in the not too distant future, as will many others...It'll be for the poor souls left to deal with. I'll be a fucken ghost....or in hell.
