For the past several years I have been using DropBox mainly to share large numbers of photos and documents (mostly WORD and PDF) with specific people. I would like to expand that, so that I can share tens of thousands of photos at the same time, all organized in folders within folders, with specific people. When I share just a few photos with just one person or a few, I use E-mail. When I want to share maybe 20, 30 or maybe 200 photos with the general public, I use FaceBook. But when I want to share 20,000 photos with just two or three people, I think DropBox is the only way to go. In the near future, I would like to share several dozen documents permemently with the general public, permanently, as though I were a library. These shared documents must be esaily visible and easily findable to everyone, especially people who do not even know me. In other words, anyone woh types in the right key words, must be able to find my shared documents easily and quickly, without needing to know the I exist or that my DropBox page exists, or even that Dropbox Exists, for that matter. My shared documents must be easily findable even for people who do not know that DroopBox exists.
