I just mean that you can only use 5 tags on a post, so if you have 5 that are really important, you won't have "space" for #minnowsunite, but I think it's a good tag to make room for. You can't follow a tag, but you can select a tag to view all of the posts in it and #minnowsunite helps us noobs locate and support each other, plus there are several whales and dolphins who like to go there looking for new accounts that they feel should be helped or promoted for whatever reason. Maybe they love the content but might not have seen it buried in another tag, or they feel like you are really putting effort into your posts and they want to reward that.
