> My latest post also talks a little about why readers trust the Medium.com URL, which may be another reason writers might gravitate to the site.

Do you really think so? So many times I've been tempted by a link to Medium, only to encounter an article that was a bloviating waste of time by a self-fellating author that took an age to load on mobile. Though I've certainly found useful articles there, I would by no means say that medium.com is a mark of quality any more than wordpress.com or blogger.com.
