It's kind of hard to believe this is not only still not a feature but that it was not available at launch. The influence of Reddit is pretty clear in the whole idea of vote driven content, and steemit ads tons of innovative value into that concept. Why would they not include one of the most attractive features of Reddit--category-based content organization?! Following users should of course be a thing, but it is secondary to utility to topic based fed curation.
With the way things stand, my content consumption had to consist of searching one tag at a time manually to see the content I want. I'm kind of surprised there are no comments or explanations from the devs on why this isn't a feature or whether it will be.
