I think it was a waste of time.
I also started to think in this direction more the last few years: If we as a socity would be better of creating less but better, we would not have facebook or linkedin feets full of waste. We would have perhaps 10 hn articles per day, 10 world news, 1-2 local news and thats it.
I would have the rest of my time 'free' of the burden of trying to make sure i'm not missing something.
Every idiot thinks something created and shared is worth while while i'm often enough think 'oh now one would care for something like this' or 'a few people might wanna read it but wouldn't act on it anyway'.
I also started to comment less. It costs time, i don't have the feeling that a lot of peole read comments and honestly, i had plenty of discussions which just stoped and there was never ever any feedback (besides 'likes' like wtf.) on 'was that helpful'.
Did i add value to our society or was it purely for entertainment?
