I'm a fan of dev.to as well as a writer. But, it's totally focused on development related things.

The super power that I see on medium.com is that it allows any topic to be published user-wise or publication-wise.

Dev.to doesn't allow us to create our own publication and make a community for a business which medium.com allows.

I'm totally in love with "publications" on medium which allows us to grow a "brand name".

But, I think reading and writing should be free :)
