Many would like to have a journal of important things that occur to them during their day, every day. Thoughts, ideas, experiences, etc. Many don’t because it can be hard. You need the discipline to make it a habit, and it’s hard to remember later what seemed a good entry at the moment it occurred.
An app you can – at a push of a button – record your short entry right after it occurred. Just say it to your smartphone’s mic and it will be forwarded to someone who will transcribe and edit it. Next day you will see all the entries of the previous day in chronological order correctly edited. You can share the online journal if you wish, with particular people or the world, and even get a printed copy for a given period as a book.
You would like to listen to some music or watch a video without using earphones, but there are others around you, and you don’t want to disturb them.
Install directional speakers in smartphones so there is a minimum of sound leaking to others.
If you want to read a new and much-discussed book (or an old classic one), what better than to have your favorite celebrity read it to you?
Publish certain books in audio format narrated by different celebrities (actors, business leaders, etc.)
As an additional experience enhancement.
The ebook reading device tracks the reader’s behavior (pauses, eye, and head movement, etc.), and when deems it appropriate based on the reader’s behavior, plays short audios (music, narration with additional thoughts or information about what he just read, sound effects, etc.)
Have a weekly online live lecture for members. Membership should be a low fee to have as many members as possible. Additional revenues from a commission from lecturers sales. Members can access replays and synopsized replays with just the main points (and the pitch.) This is less about the person and more about the actual help they provide each week.
