What are the best places to see content, news, conversations, or simply interesting websites over the internet.

Are these communities mostly embedded in social media like instagram/facebook/twitter or are there locally hosted places that are interesting for whatever reason to visit.

I would like to know, not only to view them myself, but perhaps link anything novel that I find to this community.

Feel free to post what you think fits, however obscure, even if you read this post 6 months from now!
