I don’t know if there is anything to the letter J or not. But I think these writers are popular because they know how to write and are great writers. I also know, that like in the music business, there are many great writers that are unknown. And there are those that write that think they are great. I wish I were a great writer. But I am below average at best. It does take a lot of hard work and long hours to become known in the writing world.
