The term E-Learning 2.0[23][24] is a neologism for Computer Supported Collaborative Learning (CSCL) systems that came about during the emergence of Web 2.0.[25] From an E-Learning 2.0 perspective, conventional e-learning systems were based on instructional packets, which were delivered to students using assignments, and then evaluated by the teacher. In contrast, the new e-learning places increased emphasis on social learning and use of social software such as blogs, wikis and podcast.[26] This phenomenon has also been referred to as Long Tail Learning[27] See also (Seely Brown & Adler 2008)[28]
