Steemit has helped my vocabulary..
Honestly I would have no intent to post 100% original content.
Post a few news articles here and there couple video links to cryptocurrency but I noticed that people are more interested in my personal posts or post that I make myself than anything I can copy and paste or quote.
That being said I had to stop using average words to describe things all the time to at least make my writing and look appealing and its (kinda) force me to learn more in my spare time
