I like topics first so your post could be opinion steem blog... I guess it depends how you have the taxonomy setup for yourself, there are no rules but I think the content and how the tags describe the content is more important than affiliation which is all that tribes are unless purely topical like drug abuse tribe or something they are just little isolation groups playing out of sight out of mind. Not a bad thing but also not a topic hence they are added last and also these are mere guidelines I use for myself and play hard and fast with them as is.
