This is *almost* already in place with "Categories" and the Categories you have are very nicely broken-down, but unless I'm wrong, I'm guessing that a Skuid Moderator has to assign these categories to each New Conversation themselves manually?
And the 'Related Categories' checkbox when making a new post is missing most of them.
Being able to Categorize our own Conversations would help everyone out. And obviously the best solution to this would be if it had predictive tagging or categorizing so that if i mentioned Action Framework and Chatter as I started a new convo, the rest would be taken care of.
(I know.. I know. This is a backburner suggestion, but I'm implementing features like this into my own personal workflow, and it's helping a lot!) :)
