Daplunk, on the second video, you missed (I believe) the main use case. You need to have a topic previously created that did not auto-link because the term had not been created yet. For example, you have a topic that discussed 'ranger' but you haven't created the 'ranger' topic/article yet. Now you create the ranger topic/article and you want to scan your database for where you already used that term.
I think this is where the feature is completely and totally awesome.
