I am trying to find some sort of guideline or rule to know when to use Managed Metadata. From what I can tell, if you want to have another person manage the terms, then Managed Metadata is great to use. Another might be if the terms change a lot, you might want to use managed metadata. Are there any other best practices on this? I like the idea of using choice lists but also like Managed Metadata but there has to be a method to the madness, right?
