Welcome aboard! Sounds like you've got a wide variety of interests, which is great because you should be able to find a little something here to cater to all of them. :-) Steemit itself is like an onion; it has lots of layers to peel back. Just when you think you've gotten comfortable with it, you'll discover something new and your horizons will expand again. I imagine that will appeal to the technologist and explorer in you.

Hope you have fun and enjoy your time as a member of our community!
