Just joined hubski... used to reddit, this is a bit confusing. How do you follow the book club... is there like a "subreddit" for it or something?
First of all, welcome. If you are interested in following the bookclub, in the upper right-hand corner of this page there should be a link to "follow Hubskibookclub." If you're interested in the bookclub, you may want to check out the #shortstory, #writebetterdammit, #books, and #writing tags. That said, following people on Hubski is just as important, perhaps more important than following topics. Following people allows for serendipity to introduce you to articles and information you may otherwise have missed. Therefore, I suggest checking out the badges link at the top of the page for some of the most appreciated content and then following the users that posted them. There are a number of differences on Hubski, and it can take some getting used to. If you have any additional questions, feel free to ask them, I am happy to help. Again, welcome.
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.
