I like the ideal of hubski put forward in this post. I've used reddit to find intelligent discussion of topics important to me, but I don't love the idea of subscribing to individual users to find that discussion. I don't want to join a "twitter with more characters". What do hubski users have to say about that?
That said, I can also adjust to new formats when necessary. Which users should I follow for world news, astronomical and space discussion, video games, US legal issues, US politics, EU politics, current book releases, folk and punk and ska and jazz and blues and pop music, sci-fi/cyberpunk, and Dungeons & Dragons?
