Youtube is the only one I wish I could do without, but can't unfortunately. Need to fix the car, fix the washing machine, grow tomatoes, repair your phone? YouTube. It's a necessary evil.
I'm a sysadmin by trade and thank goodness 90% of the job related internet searches I make, return results I need to read. Though most of those are StackExchange/StackOverflow/Reddit (Reddit has become a cesspool in its own right.)
I miss the days all interactions on the internet were like this. Small communities, simple interfaces, where you just enjoy the people that are there. I'm am so glad I found this place!
