I don't know if you wanted to or not, you made a very accurate publication at this time, since the tags have attracted attention lately on Steemit, because they can be a very good tool for categorizing and finding content, however, they have become something very repetitive, placing many publications under categories that do not provide any distinction, and that consequently do not work to find the content that any curious reader would like to find.

You have correctly said that there are tags that are not necessary, for example: club5050 and burnsteem25 could be last in a publication and not first since they are elements that are always checked when a post is verified.

The first 5 tags are very important, it is assumed that on a platform with hundreds of posts, any reader will need a way to find information, and that is where the usefulness of tags begins.

In these times of free curation, curators, for example, need to be able to find publications that they are looking for, for example: art, creativewritten, food, etc, etc... Tags are useful for this.

Therefore, each author should be able to use the tags so that they can be seen. That is the reason for its use.

However, because there is no proper use, many publications are lost from being seen.

The tags are supposed to go in order of importance, the first should be what your post is about, and then a subclassification, and etc. For example, this post of yours would be something like this:
#contest, #tag, #steemit, #indonesia and #steemexclusive.

I invite @oneray, who has a very interesting post about it. And @event-horizon and @mesola 🙂
