You're one of the first other people I've talked to on here who makes use of Medium's speechify feature. Ever since my first article I published here, I've actually been making use of it. It's a great way of hearing your piece through new ears, as you say. It's become an instrumental part of my editing process at this point. Not only does it let me become a vicarious listener to my own work, but it helps me to catch the errors I typically scan over in my proof reads: a missed word, or a repeated "to" are far easier to catch when spoken. Nice to talk to someone else making use of this wonderful feature! Great piece.
