I believe you should only be asked to follow or like somewhere if you the audience benefit.
The ones I am most active on, and so the ones most likely to be of interest to you, are:
My LinkedIn profile where I post links to articles I find of interest.
Reddit. I love Reddit, it’s a great place to get links and discussions on articles and see converstations. I tend to be active on /r/writing and /r/screenwriting – get in touch if you want to know my user ID.
Then there is Twitter. Follow me on Twitter if you want to know when I make a customer complaint to the only place where you get a response.
