Persona Paper is Better than MyKites
In my opinion Persona Paper is a better writing site than MyKites because it allows for links to be placed in the articles. Sometimes there is relevant links needing to be placed in as a hyper-link. MyKites doesn't give the option for a hyper-link, so you'd have to leave it as the URL form, and I think even this is discouraged.
Many of us find motivation to use small writing sites to promote a blog or video with some of the post we write, and Persona Paper allows this with their more professional editor box. MyKites is a nice looking site and I'm glad it's around, but really it's a social site more than a writing site. I don't really get motivated to be social on-line. Hopefully they both pay once we reach the mountain top of payment min.
