Quality over quantity, that is the secret! To help you out, if you like football and make a post about it you may wish to use the tag #sportstalksocial and if you make a post regarding Science Technology Engineering Math (STEM), you may wish to use the tag #stemgeeks. In using these tags you can earn tokens along with STEEM!
There is quite a learning curve yet, don't be discouraged... there are many folks that are willing to help. This post by @whatsup is a fine example. If you use the Discord you will find many folks that will help you along (networking and finding folks with similar interests is paramount in finding an audience)! There are two resources that you may find very helpful @shadowspub and @steemterminal.
Just a little help to get you started. I have been a STEEM user for 2 years and I am still learning. Good fortune on your Blog here on STEEM and welcome!
