Great article! I don't know if anyone mentioned it yet, but Miraquill is a very good poetry platform. They used to be Mirakee. The site is simple and has a feed as well. You can design your poetry and quotes for free(other design elements require a premium cost). The biggest plus of all is the community! You get so much feedback. I may write about this site soon. Also, they are available as an app, the website is missing most features.
