Tagging is simply not how OneNote does things. If you're looking for that, use something else. Where OneNote excels is in giving you a tool to organize and manage your structured content. Personally, I prefer that paradigm since it gives you so much more control as well as allows you (in my opinion) to organize your thoughts and ideas better.
Isn't folder structuring a subset of tagging? How can it 'give you so much more control'?
Not saying that the extra freedom from tagging is only good, but it sure is more flexible than folders and tabs.
