We've reached this far by listening to our users. Would love to take this further and get any feedback from HN's detailed community.
What sorts of users have you been listening to? How does it make them more awesome?
In terms of document types: - Templates - White-papers - Samples - Reports - Policies and procedures - Articles - Forms - Checklists - Research - Project deliverables...
In terms of formats: - PDF, OpenOffice, Excel, Word, Powerpoint, etc..
The users we've tested with were on the sell side of things: individuals/organizations that had documents to share/sell/distribute.
