Currently, you can find a huge variety of services of social bookmarks, including clones of such well-known projects such as Digg and the like. Resource Buzzup represents just such a clone-based technology news, but the topic Buzzup Docs much more interesting than the main project.
The authors of the service position Buzzup Docs as Digg for documents downloaded from services like Scribd, Docstoc, Issuu, Calameo, eDocr and Slideshare. You can upload your document in one of these services to insert a code integrated into the above-mentioned Buzzup Docs. Interested users will be able to flag such documents as interesting, in voting for them - all as usual.
Naturally, the papers are divided into several categories, including the category "business", "Culture," "technology", "entertainment."
Actually, Buzzup Docs is an aggregator of documents from the above-mentioned services, with some possibilities of social services bookmarks - the idea is extremely interesting in itself, but perhaps the creators to think about some changes to the interface of the project to make it truly unique.
