Hi Susan! Man, you have a lot of really cool talents! That's a terrific facet on here! I would say write about as many of the things you do as you can (or make videos about them) the more varied the better!
As far as YouTube, you can definitely post YouTube videos on here, but it is much more effective to upload any of your Steem-specific content to d.tube! It is the blockchain equivalent of Youtube and all of the serious vloggers on steemit are all using it! It is kind of a pain to use right now, but it will def appeal more to people following you and it helps grow Steemit too!
I can't wait to see what you do with your blog/vlog! Good luck!
Thanks much :) and yes, I have heard about dtube. Is it worth it?
I definitely think so! Steemit definitely seems to reward users that invest in the platform and d.tube is part of the Steemit platform. They are trying hard to compete with YouTube, and though the site is still in its infancy, it's also a great time to get content on there. It's akin to having been able to start using YouTube when it was brand new, and building a brand there!
