Personally, I find the blue checks on Twitter to be fairly valuable. I’ve never actually read them as a status symbol but just as a useful tool to tell me if, say, a candidate for the House of Representatives is really a candidate for the House of Representatives.
I’m not much interested in what celebrities have to say, so I rarely read their tweets anyway. Just not part of my Twitter experience.
As to Medium, I know a few well known authors write here, and I often enjoy their stories. At least so far, I have never felt the need to have their identities verified because it’s pretty obvious they are who they say they are. If the Julia Serano on Medium was an imposter, I don’t think they would last very long on the platform.
But then, the pool of writers on Medium is vastly smaller then the pool of commenters on Twitter. As Medium becomes larger, perhaps it will be less likely that fakes would be easily sussed out.
So if you reach a point where you believe verification is necessary, I certainly have no objection.
