Kathleen Schmidt, publicist at www.kmspr.com, discusses the new social media platform, Medium, as well as other social media platforms that may be valuable to authors. The biggest social platforms for authors are Facebook and Twitter, but strong opportunity exists on a new platform, Medium--if you can get invited. Medium features high-quality content from "names" or high-profile people. Kathleen Schmidt believes Medium is an excellent platform for visibility, complementing publishing placements on Tumblr, blogs and traditional media. Schmidt recommends Medium for authors who are skillled at writing op-ed pieces.
