If you have a good time then it's not wasted, and if it helps you get useful info or inspiration for new projects then it's even better.
Honestly I go here for drama in the comments. And for the feeling that I know something before all my friends do. But the main thing is sometimes you can find a great article that pushes you forward as a developer (or even better as a person) and I don't want to miss it.
This site is filled with jaded millionaire nerds who believe the world can't ever get better. I'm the exact opposite of that but I stay here because sometimes you can find people who really know what they're talking about, and that makes it worth every minute.
