Oh hey I have a piece of advice. You would typically always want to use at least one or two of the most popular tags relevant to your post. Tags are pretty much the only way someone who is not already following you will find your posting. I would recommend checking out this link and sorting by # of posts (click the column header to sort by column) to get an idea of what the most popular relevant tags would be. You should definitely use #education which has 18,000 posts; for reference #steemiteducation has 6,000 posts. None of your other tags even appear on the most popular tags list. Cheers - Carl
