Reddit

In addition to videos, games and communicative technology, the way in which we browse, comment, communicate, share and elicit information continues to evolve with user-led content creation sites like Reddit. This site is a platform for online communities such as citizen journalism where users post the latest breaking news, and form sub-threads, launching new communities designed to narrow the focus on a particular topic while broadening the scope of discourse. Each thread has a set of rules for users to negotiate before participating, and some threads inform users of content which may be inappropriate giving rise to the popular NSFW tagline. Popularity of each topic is determined by user participation, up-voting or down voting, similar to Google's Page Rank system. The collaborative filtering of content by users helps spawn thousands of communities within one domain, often providing some individuals their entire selection of information in one space. Think Walmart for the online prosumer of knowledge and collaborative media.
