I don't understand the attraction to this service. For me, scanning the notebooks would be good if there is some way of intelligently cataloging it, and make it searchable.

I avoid writing stuff in my notebook that I know I need to find in the future. I put into in an email and search it via Google search. Drawings and sketches are different categories. I would scan then and attached it to an email. The message of the email would provide context.

I think what Mod is providing is only half of the solution. At the moment, it is the same as "only to forget them forever when I leave it in a dusty box somewhere", only digitally. For me at least.
