Ok, thanks for your enlightening answers and for upvoting my hidden comments. I'm currently not sure, which way to choose now, but I will do my best to find one that works for me.
Even if there is not much new to discover in SteemWorld currently, I made good progress so far and I'm sure that, when I'm done with the things that are waiting in the pipeline, there will be more investors convinced about the value of my work.
Since I'm a purely creative coder, I'm having a hard time with presenting planned features. Most of the SteemWorld has been built intuitively in a creative flow without much planning and this is how I function best.
