I can understand your dislike about all these tribes. On the other hand the tribes and the tags allow to target your readers in a more precise manner. In addition, using the tags increases your projection surface. With every tag that is used, a post is visible on the according condenser. If I use the tag palnet, my post will be visible on palnet.io. So the more tags are used, the more the visibility increases. If I take this post, it got nowhere on steemit but on ctptalk it was a trendy post for some time and was therefore very visible.
I believe that if you write a specific post that "fits" a tribe it's worth to use the according tag. For example if you write a post about investment in cryptos, it would be a mistake not to use the steemleo tag.
