The criteria that you take into account are interesting, and due to the diversity that #pob offers to its users, a wide range of topics can be covered, but if I'm honest I find some irrelevant topics such as sports since we have a tribe specialized in That, and I see users who to get a little #pob leave their post about sports, and if the fact were that the content would vary but not since 80% of their profiles are only sports-related content, they are only looking for a benefit own more than something collective!
