Thanks for the explanation! Is the book community large here? I run a subreddit where we compile a daily list of free kindle books "that aren't crap" that y'all might like here :)
Like humanodon said, Hubski itself isn't very large. We have around 10k users and far less of those are active. It makes for an intimate exchange, one in which you actually get to know the people here and have many conversations with the same individuals. That said, if you know of others that would be a good fit for our community, then you ought to invite them to come by. We'd love to meet all of you. Good luck with that subreddit, it sounds like a cool service to provide to people. If you have any questions about how to navigate hubski etc, like I said, feel free to reach out.
