I've rather soured on Vocal (yes you can post the same article on both sites). The unfathomable way they determine views escapes me. Stories that I know are being read, based on Facebook comments and Twitter responses (which aren't an excellent measure because on many topics like political ones, a lot of people respond without reading the story). But my experience is that they pay a lot less than Medium. If I didn't value my time, I'd continue posting on Vocal which theoretically should pay more based on not being limited to their own base of readers, but I don't think it a good use of my time.
