I do sometimes cross-post from Medium. Usually the flow is: post to Medium and publish it via Twitter, Facebook, and forums, post the link to Reddit the next day, and cross-post here on dev.to for extended reach (ThePracticalDev's Twitter account is a great distribution channel too which you get for free!).
Both Medium and dev.to releases me from the burden of (re)designing my blog, so I can focus on writing instead. I am currently in a dilemma of not wanting dev.to to provide customization options, but there are some tiny parts of the design elements that are not to my liking... but I think I can get over it. Still thinking of permanently making the move to dev.to as the main channel but currently still not, uh, courageous, enough :D
