It's something I regularly recommend to new steemians as a way to get a few SBD's to start doing post promotions to build their brand.
It's also a great way to grow a circle of friends that give you continued support as you grow on Steemit.
Plus it's just more fun than twitter.
The key is to monitor your posts and see if they are getting enough upvotes and comments otherwise you may be better off following, upvoting and commenting.
