Hi Zeus, first off /u/AdelleChattre did bring up a good point in regards to the current way the recommendation engine works, and those tags do indeed help our algorithm make proper associations between the content within each tribe and what tags are taken into consideration when listing the highest association tag links. Having said that, we are indeed looking to overhaul the whole recommendation approach as we move towards creating better community management tools, so expect things to shake up in the coming months when it comes to tribe related functionality.

I won't reveal more at this time, as we are still in the process of laying out the ground work for the update.
