For what it's worth, it should be noted that we aren't trying to compete with reddit. Reddit exists and it's good at what it does. If you want to follow a topic, a subreddit is a good way to do it. Early on we decided that we wanted Hubski to be about people more than about topics. Tags are a great way to introduce yourself to the site but ideally once you are familiar you will start following other users. IMO, this is far preferable to following topics. It allows for familiarity and a more congenial exchange of ideas and information. Following people allows for the serendipitous discovery of content that just doesn't occur when you are walled in to a specific topic. But if you are looking for specific information on Dayton Ohio, then r/dayton (just an example) is probably where you want to be.
It will not seem obvious at first, it takes some time, but what you will find is that once you follow some users you will become more familiar with them and more often than not some actual friendships or at least a mutual respect is formed. It's been pretty cool.
Welcome by the way!
