Like many others- I've pondered this and asked about it. I have two niches that can be called passions. Completely unrelated. Thought about doing two separate accounts to split them, but that seemed inefficient.
Thus far all of my investment and financial posts have been titled "ScaredyCatGuide to Investing - name of post" and all of my poetry and creative stories just title whatever it is they are.
Hoping that will create enough divide to cater to my users. The creative stuff gets way more play. The financial stuff doesn't seem to have a big steemit audience, but I still want to write it.
