The first social networking tool that I found was: DocStoc

DocStoc is a free online document exchange database and social networking site. It allows users to store, search and share any type of document. These documents can be anything from Word, Excel, pdfs or PowerPoints. It is a similar website to Flickr.com for posting pictures and YouTube.com for posting videos. On this site not only are users able to post their own documents, but they are able to categorize and use other documents that have been posted.
