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.
Create a never-ending list of stories.
An app where you enter you airplane code and your seat number, and you can then do two things: read all the stories of people who sat there before you on other flights, and add your own. Each seat on each plane has an unlimited number of stories you can browse on a timeline. Stories about the people who sat there, about their flight, unrelated personal stories, any kind of personal story.
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.
You have patterns you repeat when answering emails and otherwise messaging. These are similar to other peoples but have your style of expression. Today you can already automate these on many devices by using snippets and a shortcut. The only problem is that they are always exact copies, so answering the same person twice will reveal this fact.
A smart snippet software that, while you are typing, analyzes your words and suggests an auto-completion of the whole sentence and not just one word. It will do so with a slightly different variation based on how you started your sentence and your writing style. As you continue writing what it suggests changes until at some point, you choose to use it and complete the sentence or even a whole paragraph.
