“digital technologyis changing both how words and ideas are created and proliferate, and how they are
studied.”
Social Web 2016, Davide Ceolin

social media is a rich resource that
provides “a fuller picture of today’s cultural norms,
dialogue, trends and events to inform scholarship, the legislative process, new works of authorship, education and other purposes.”
Social Web 2016, Davide Ceolin

The Onlife Manifesto“The ever-increasing pervasiveness of ICTs shakes
established reference frameworks through the following transformations:i.the blurring of the distinction between reality and virtuality;ii.the blurring of the distinctions between human, machine and nature;iii.the reversal from information scarcity to information abundance; andiv.the shift from the primacy of entities to the primacy of interactions.” [Floridi et al., 2015]

communities (not institutions)• internet provides a good platform for emerging social

New Means of Communication
• beyond email, text messaging & mobile phone
• asynchronous (not requiring real-time response)
• a lot of communication seems irrelevant & trivial
• some can be helpful & interesting• celebrities & organizations use it
to communicate with their fan bases & audience
• many people (especially the teenagers) addicted to this new mode of communication

New Form of Communities
• Social Web sites are in essence online communities• Groups around a number of natural attributes of
the members, e.g. schools attended, employers, cities of residence.
• Groups around any type of interest, hobby, or cause, where people can help one another with information, advice, and personal networks
e.g. the role of communities in the Arab Spring, unrests in Turkey, Ukraine, Russia Olympics, Occupy Wall Street, etc.

collaborative coding

New Source of Entertainment
• Most people need to entertain themselves to enjoy life, to recharge themselves, and to pass the time
• That’s why people have accounts on several social Web sites, and visit them rather diligently and regularly
• People got catapulted to worldwide fame after they appeared on YouTube

New Venue for Self-expression
• a surprisingly large number of people have had a strong desire for self-expression and desire for self-satisfaction that comes from helping others
• a major reason for the Wikipedia success, where more than 10 mil articles have been contributed by thousands of volunteers without financial incentives
• the personal posting many people do appears to help them to derive a sense of ‘self-assurance and belonging’

New Economic Models
• “Sharing economy (also known as shareconomy or collaborative consumption) refers to peer-to-peer-based sharing of access to goods and services (coordinated through community-based online services).” [Hamari et al. 2015]

Expressing Opinions• Allowing members to leave comments on
the content, voting by ranking (3 out of 5 stars), or marking as ‘‘favorite,’’ flagging as spam/inappropriate
• Sites use different ways to present and organize those comments (hierarchical, timestamping, counting, etc.)For example, Digg has two buttons, ‘digg it’
& ‘bury’Similarly, YouTube has ‘like’ and ‘dislike’ Also Facebook announced a ‘dislike’ button.
