It seems as if though you're superimposing reddit's content mechanics onto this site. The entire purpose of Hubski is to allow user to tweak their news feed to their liking. People will follow people who's content they enjoy. People ignore tags and people they do not. From this mechanic alone, users are allowed far greater power over the content they view than any other site I can think of. Why is it that you're so concerned with the "trash content" that you have the power to remove from your personal feed?The nice thing about Reddit is that no matter how large it gets you can always find a nice, cozy, small(ish) subreddit to talk about whatever topic you like after you unsubscribe from the big subreddits of the same topic, but you're never really free from ideas you don't agree with.
