It seems Stack Overflow is fiercely opposed to such changes. So I am posting here out of naive hope that may be some startup will find this idea worthy. It's still looks very consistent to me
You'd laugh at me, but I am still using a LiveJournal clone - Dreamwidth. This pre-social network is quite comfortable to be in. It is, so-to say, non-invasive. You'd never see a post from someone you didn't subscribe to. There are no ads. No mental viruses to pick-up. Just what a social media is meant to be for ordinary people to keep in touch with some friends. And of course there is no mobile client to ring a dozen times a hour. I just read my friends list when it is comfortable for me.
And I visit my facebook account weekly, via desktop browser, only to see what's up with my friends hanging up there.
I very seldom do likes, as I know that my likes could show up in my friends' feeds. There are NO notifications from social network or media on my phone. I call it "information hygiene".
And yes, like others mentioned, I've got A LOT of spare time for books, hobbies, movies etc.
