I was hesitant to start on social media mainly because of fear - that I will be way in over my head - I started with Twitter and what I do is hit the Twitter button on the article I just published so it is simultaneously posted on Twitter - sometimes I hit the FB and In buttons as well depending on the content -

It is convenient as everything is on one page -

I would suggest you pick a social media platform and sort of ease your way into it - there are lots of Mediumites everywhere so you won't lack for friends 😊
