Hey, thanks for the feedback I appreciate it. What I would suggest is following a few tags to begin with. Once you notice certain users that post content you enjoy, follow them. Eventually, you're feed will be comprised more of people you follow thank tags. In my opinion, aggregation can function similarly to actual relationships. I may meet someone at a concert for a band I love, and become good friends with them. Overtime this friendship will revolve around more than just that one band, and perhaps more than just music. I think Hubski can work this way too. But if you're interested in a more focused experience, perhaps just following tags is the way to go. Hope this helps.
I think that's a great idea, thanks for the analogy you made! I'll give it all a shot, either way I'm happy with the site so far!
