It looks really nice, what are your use cases? Do you expect to build a Scribd competitor?

How will you fight spam? (when I search for a book I'm interested in, I get a lot of Google Docs and Dropboxes and stuff with the search terms and a link to shady sites)

And legal risks? I'm pretty sure many of the documents I'm seeing are not free.

Are you based in Lima, Perú? Are you thinking of going to Startup Chile?

PD: My native language is Spanish, but for those browsing for English documents (probably most of the HN crowd) do you provide any functionality?
