So, I'm trying to understand why the Hubski wheels at the top are the way that they are. They allow you to view posts with a precise number of shares. Generally though, people don't want to view posts with a precise number of shares, but post with at least a number of shares. Like, I might want to be able to view all posts with at least 4 shares because I believe that posts with less shares are unlikely to be worth my time
Maybe it's not for everyone, but I like being able to find discussions that are just starting out. Of course, dots are not always an indication of good discussion, only of shares. I've been able to find ways to make hubski suit my needs and from what I've seen, others have too. The "best way" really seems to be something on the minds of the developers, which I appreciate. For me, that means cycling through the methods available to find things I like.
Are they unequivocally the best way? Well, that implies that there even is a best way, which is a whole discussion in its own right. For now, though, we'll just consider the wheels. Are they an option? Yes, of course, and I think they should stay as such, even if some users don't find as much utility in them as in, say, tags. Like @humanodon intimated, users can cycle through the methods available to find what best works for them individually.
