Docstoc is taking aim at finding and sharing documents through its free online document exchange system. This social networking site will allow users to store, share and search any type of document. Whether it's a Word, Powerpoint, Illustrator or PDF document, users will be able to post, categorize and also rate documents.

The service is said to be similar to Flickr or YouTube in concept, but targets three applications, namely Business and Legal, Educational, and Self Expression.

Docstoc is currently in beta testing mode, we are trying to get in to take a peek, and will see whether they want to be a part of our Free Invites program.
