If you want to be a successful author you need to be so much more than a writer. Recently Twitter has been getting some bad publicity, but it is still valuable to writers. It is the social media platform, I have had the most reads through. Twitter has a huge writer and blogger network. The people I have interacted with have always been supportive and friendly. Yes, the platform does have a large percentage of trolls but with the block option, this should not be a problem.
Great points. In the same way, the points apply to vlogging and blogging.
