The implementation isn't complicated at all, and I don't think I ever said it needed to be. Heck I could craft something up in half an hour or less, have it in a day later, done.

The problems though have already been highlighted. There are going to be posts that straddle 2, 3 or more of the sort of sections we're talking about, especially in the case of troubleshooting posts. There's no getting around that no matter what sort of structure is created.

The complications, then, are in the aftermath of change. Where the Law of Unintended Consequences reigns.

So the best we can do is identify, at a very high level, the best sort of structure to begin with (is there anything remotely near a clear consensus on that yet? I can't tell) and then as we drill down into details (ie, opportunities for posting confusion) we identify and implement the best solutions for managing what we can with regards to "topic bleed".

Or least worse solutions, as the case may be.

And I would truly love to be wrong in that above assessment.
