I'm a new steemian too. I was introduced to it by a friend. I don't know much about it myself. I do know it is much cleaner than any other social network I've seen. I also inspired me to get my creative juices, that were buried a long time ago, to start flowing again. It's a slow start, but I done a couple posts and have a few more in the works. Good luck and don't give up.
