2.0 Alphabet
is for reddit, where users submit links to content and then vote on the links, so the most popular items bubble to the top. Similar sites are Digg.com and Newsvine. A study released in September 2007 by the Project for Excellence in Journalism showed a wide divergence in what the so-called "mainstream media" considers to be important and what "the masses" perceive as worthy of attention. This is proof.
"The site has discussion areas in which users may discuss the posted links and vote for or against others' comments. When there are enough votes against a given comment, it will not be displayed by default, although a reader can display it through a link or preference. Users who submit articles which other users like and subsequently "vote up" receive "karma" points as a reward for submitting interesting articles."[Wikipedia]
