Reddit is a social news site that allows users to rank online stories. Reddit is a great tool for finding non-mainstream news, commentary and scholarly information. Reddit–as described on its about page – “is a place friendly to thought, relationships, arguments, and to those that wish to challenge those genres.” Running off of an open-source system, reddit readers, “redditors” vote on which issues or topics are most interesting. The topics with the most votes rise to the topic of a discussion thread and those with the least votes sink to obscurity. It is a democratic system for sharing news, asking questions, and engaging in myriad topics with people across the globe. (There are education-related reddit pages — http://www.reddit.com/r/education).
Here is an example of searching Library in Libraries.
