It would be interesting and might be useful to understand the reasons.
A study that tries to find out all the reasons why many people write a book and put it in a drawer, never showing it to others and never publishing it.
Many people write, but nobody ever sees the fruits of their work, many times because they are afraid.
A website where users can publish a sample of their work (maybe a chapter from their book) – anonymously, and others help them by reading and reviewing. The anonymity is key.
You would like to write a blog post, but you are not good at writing, have no experience or time.
An app and website where you can press a button, speak into your device’s microphone (or upload a recording) about the subject – anyone can speak – and get an article written based on your recording. You should talk about the subject and include instructions to the writer and editor who will make this into an article.
You need to write an important email. You know what you want to express, but it’s complicated and nuanced and multifaceted. Wouldn’t it be convenient if like in old times when many didn’t even know how to read and write, you could have someone do that for you cheaply and quickly?
On online service where you can get such a writer online immediately, talk with them to explain what you want expressed, facts, subtleties, feelings, etc., and have them write it for you and with you live online. No waiting, and fast results.
