Figshare's aim is to make unpublished research and data accessible by publishing it using a liberal creative commons. Research is posted in a citable manner. Recognizing that some research needs to be kept private, Figshare also provides account holders with a free gig for private storage. Uploading is straightforward and Figshare accepts any file format. Researchers uploading material get a profile page, and are encourage to share as much as possible to increase their impact. The Figshare REST API amplifies the impact of the shared data by giving developers access
So, you're trying to share some files with someone who only has access to an old version of Word. Or maybe that Microsoft-hating friend of yours who only uses WordPerfect. Perhaps you want that old-school ebook to be an epub, rather than .lit. For any of these problems, there are desktop apps that work, of course. However, sometimes you want to be able to do that within a program. If so, Doxument and the beautiful Doxument API are what you need.
