For all you new users, I say give it a week. You are fresh off the boat and want you subreddits. We understand. But give the way Hubski is set up a good long shot bc it works well. Trust me. I've been stuck over here for almost a year. The first thing I did was follow tags as well. But once you start getting used to the idea of following people and recognizing everyone's unique personality, you'll forgot you even made this request.
This really sounds like a pretty sweet idea, and it excites me that this system does exits here. However, I'm curious what will happen if/when the population of this site starts to grow. I don't know if a system based off recognizable individuals will endure a large user base.
Twitter seems to do fine with a huge population. You find your niche, I suppose. Like thenewgreen and mk have said, hubski is always open to ideas and discussions as the site grows and the population grows. I think that there will be challenges but as long as the community continues to offer intelligent insights, it should be alright.
