Welcome @mordekaimoriarty (wow that's a long name! :) )
What a nice and interesting intro of yourself. I think you will find the Steemit community very supportive and respectful.
I didn't know how I was going to shape my presence on Steemit either - I think that a lot of people feel this way and probably still do. Steemit is a good place to learn new things, meet new and wonderful people and explore the many interests you have.
So welcome! Enjoy
