Just know that every time you write material and use a new tag/topic, you will be attracting potentially different followers with different interests. I don't know how much cross over there actually is and I have yet to read any post where someone has addressed that particular marketing topic. If you want to keep all your followers content with your work, I can tell you that it takes consistency. So, you'll always be juggling between writing about various subjects at any one time. I just wrote about a gaming computer that my husband found at the dump and decided to resurrect because it was just loaded with perfectly functioning components. It was really well received by the Steemers who saw and took the time to read it, but it was my first time writing in the "gaming" tag/topic. If I wanted to pursue this and develop a following in this tag/topic, I would have to keep writing pieces for it. Every time you write something new in a new tag/topic, you are basically starting from almost scratch. I say almost, because they will be some of your followers who will be interested to know what you are up to and curious.
