Interesting idea, Douglas. We'll discuss it a bit. There may be a new Category or something we can do to preserve these types of topics as opposed to making them KBs. 

Supplemental thoughts:

It should be like a locked topic or KB article - changes and addendums are only made by ST or the author after ST review.   If you want to discuss the current revision of an article or the toolkit that it describes, open a forum topic.

When selecting topics for inclusion, ST makes the final call on whether the topic is of long-term interest to its community.  You might create a process for authors and others to nominate for inclusion.   I have written several items that I thought were important, but sadly they gathered no interest or negative interest.
