There is few good reddits with good/decent moderation (deleting silly memes and off topic comments, /r/AskScience , /r/fitness and /r/DepthHub/ comes to mind).

yes, and where does one find that type of friends :/

The easiest way is probably through a hobby, in the widest sense. Be it a Science Fiction club, a HN meetup, a charity that helps connect disadvantaged high school kids with technology and programming, toastmasters international or some political activism. Basically any thing that involves meeting other people, and, as a filter, requires a certain minimum level of commitment and getting-off-your-ass.

If you are in Germany or Britain, I can give you more concrete pointers.
