The value I provide is synthesis of a lot of educational material that exists out there into a coherent package (a book). In many ways, my work is similar to what linux distro package managers do: ensuing prerequisites are covered before the main package is installed.
I remember hearing one of the early Internet/www inventors saying the Internet will allow people to "live from the fruits of their intellectual labour." Does anyone know who this was??? With eBooks and print-on-demand this is finally possible now. I would encourage everyone with deep domain knowledge about a subject to start writing about it and publish a small book. I think "information distillation" is of great value for readers. Feel free to email me if you need help/advice with the publishing stuff.
