Hubski is a great place for slacking off, but NOT a good place to be a dumbass. You're following some good people though. It will make you smarter and maybe broaden your interests. There's some people on the site asking big metaphysical questions. Maybe you don't see them in your feed though.
Ehh, everyone can be a dumbass sometimes. Teenagers are just predisposed to being one. It's the way our brains are wired. It affects our ability to understand and think about long term consequences. Its actually safety mechanism of all things. It helps you leave the "nest" and strike out on your own. I've not had too much chance to play with who I'm following yet to get quite what I'm looking for. I haven't put in enough time to do that. I've got a other responsibilities and distractions keeping me away.
