Well, what I can say is that I spent my entire Hive journey understanding that if there are 10 space tags, we can use 10 space tags. And what counts here is common sense, really. I learned early that I shouldn't use Leo for "non-Leo" topics and I do the same with other tribes and communities (like Stem for example, which I only use when I'm going to post more academic and complex topics), but I can't see how the VYB and POB would not be in ALL of my posts. So I suppose your hints are not for people like me who are frequently using these tags and experiencing the day to day of the community, but for really freeloaders, who never show their faces but always use the tags.
