Welcome! Commenting and getting a feel for things is always the best way to learn. You'll quickly find out what is frowned upon, and what is praised.
Steemit is a fun place. If you are really passionate about a topic, publish something you wrote... remember photos. Text itself can be boring.
I've been here since July 4, 2016 when it first opened to the public. My first FAQ earned $4,000 --- but that is when STEEM was worth $4
Today, STEEM is worth around 20 cents or so... but it doesn't matter. We're on an upswing and things are getting better all the time.
There is just something about this place that "feels right". I love it here.
