The fear of missing out is probably a big thing as well. I tend to gravitate online for breaks at work, but not being on new social media, it’s irc and maybe forums like this. It’s super easy to then get stuck.
Twice so if said media is also needed for work, but contains inane Trump tweet BS as well (see: irc).
I wonder if there are studies from before the age of smartphones on online services being detrimental. Anyone?
Also doing StackOverflow for cheating is something that may hinder learning, but that’s a different problem.
