Welcome to steemit! I can see that @brittandjosie covered a lot of the highlights, so I won't regurgitate what she said, but, I hope you are surfing, checking out the posts and the tags that interest you. I was surprised at the people I met and the different cultures that opened up my world.
It is a wonderful place and I know you will find the niche that makes you most comfortable. Don't be afraid to ask questions and in short, have fun! I did join the @minnowsupport project when I first came and found it to be helpful to newbies.
