Web 2.0 tools have the potential to support social inclusion, but several challenges must be addressed. Learning and skills acquisition can promote social inclusion, but require active engagement from individuals. Projects using Web 2.0 have experimented with different intervention concepts, but often face barriers like overcoming resistance to change from organizations and professionals. Tools alone do not drive inclusion; social barriers must first be addressed and people convinced of the value of online social and learning activities. Impact is difficult to demonstrate under tight funding timelines.
