I think tags only prove beneficial when you have a very well defined purpose. More concrete, I think the number of tags has to be fairly limited and the logic behind the tagging scheme should stay consistent forever. One example of tags being superior to links is that you can search files with logical queries. For instance, a family member asks you to send them a good portrait of you for whatever reason. You may want to make sure that it is somewhat recent. However, you're willing to take one that is two years old if it looks better. Then you could search for: #portrait & #me & #2017 & #2016 & #2015
