I strongly agree with you. When you follow people who are not adding any value to the community you are making yourself distant from the good quality posts, you'll miss a lot of posts related to how the platform works because of thousands of useless posts in your feed and become unable to understand the platform completely.
If you want to be followed by the shinning stars of steemit, improve the quality of your work and do sincere interactions with others you'll automatically attract quality people towards your blog.
