This is one of the things that I am doing currently. I am providing ideas and tips to grow as a writer. I am emphasizing the power of giving value before getting it. I have already written 2-3 different articles for this.
Another thing I normally do is from every article find out possibilities of picking of areas which can be expanded to write more articles. For example, in an article taking about 10 things to do to increase followers to keep it short, I might have explained things at a higher level. Next day I might pick up one out of the 10 things and elaborate on them with proper examples and more actionable tips for the readers.
