Hi Henry, welcome to steemit! It sounds like you will have some interesting things to post about, and will add value to steemit.

From your post it also sounds like you are well aware of the need to get involved in the community! Like any other social media platform, it usually takes time to gain traction here, but the more you engage with others the faster it will happen and the more rewarded you will be (literally and figuratively).

It is a great and welcoming community, and I hope you settle in and enjoy your stay.
