- Before 1997: AIM, ICQ, Classmates.com 1997: SixDegrees.com - combining all in one (2000 the service went offline) - not enough user base, not enough interaction 1997 - 2001: AsianAvenue, BlackPlanet, MiGente, LiveJournal, Cyworld (Korean), LunarStorm (Swedish) Friendster - a social complement to Ryze to compete with Match.com - online dating site early adopters: bloggers, attendees of the Burning Man arts festival & gay men 300,000 users in 2003 and it couldn’t handle its rapid growth started restricted access to profiles, e.g. not more than four degrees away "Fakesters": fake profiles representing iconic fictional characters: celebrities, concepts only a few managed to succeed- at the time of the burst of the internet bubble (after 2001); ISPs, AmericaOnline ... value was not clear all started with user profiles and connections; from 2003 also media starts playing a role failures: Google's Orkut, Microsoft's Windows Live Spaces (MSN Spaces)
- The time of: YASNS: "Yet Another Social Networking Service." (Clay Shirky) After rumors emerged that Friendster would adopt a fee-based system, users posted Friendster messages encouraging people to join alternate SNSs, including Tribe.net and MySpace (T. Anderson, personal communication, August 2, 2007). rumors that they will ask for money - so people turned to other services - allowed others to surface passion and interests start to surface also failures also from the big ones 2001: professional networks - Ryze.com (San Francisco business and technology community), Tribe.net, LinkedIn professional: LinkedIn, Visible Path, Xing (formerly openBC) passion-centric: Dogster (dogs), Care2 (activists), Couchsurfing (travel), MyChurch (christian), Flickr (photos), Last.FM (music), YouTube (video) MySpace to compete with Friendster, Xanga, AsianAvenue; 2004 massive popularity (bands, teenagers); 2005 News Corporation purchase for $580 popularity in Philippines, Singapore, Malaysia & Indonesia

- As his animated map shows, over the last few years Facebook has cut down the number of top social networks around the world from 17 to just six. More specifically, there were 17 in June 2009, 16 in December 2009, 14 in June 2010, 11 in December 2010, nine in June 2011, and six in December 2011. Here are the remaining six: Facebook, QZone, V Kontakte, Odnoklassniki,Drauglem, and Zing. Between June 2011 and December 2011, Facebook managed to conquer Netherlands, and with it the whole Europe, Brazil, after a long struggle to overtake Google's Orkut, as well as Japan (although a large part of Japanese networking activities are on mobile, including Gree, Mobage, and Mixi). If you remember that Facebook is still banned in many countries, such as China (the world's largest Internet population with 500 million people), the service's dominance is certainly impressive. If this trend continues, it won't be long before the social network is king in all the countries it can be accessed in.
- The social media sites Facebook, YouTube, and Twitter are frequent targets for censorious governments. This map from Mother Jones shows which countries restrict their users from accessing these sites. China doesn't just block access to Western social media sites, it has also cultivated home-grown alternatives that are under the thumb of the Chinese authorities. These social media sites enable users to engage in relatively unfettered discusion, but the providers are required to participate in an elaborate monitoring and censorship regime to ensure that sensitive topics do not receive widespread discussion.
- - the world is composed of networks, and now they have means to communicate across geo boundaries
- "privacy paradox" lack of awareness of the public nature of Internet (safety of younger users)reconstruct users' social security numbers with profile info, e.g. hometown and date of birthfrom freely accessible profile data - craft a "phishing" scheme appearing from a friendusers' ability to control impressions and manage social contexts, e.g. "News Feed" could disrupt users’ sense of controlno flexibility to handle conflicts with friends with different conceptions of privacy
- One of the amazing things about the internet is the way it permits the collection and aggregation of large-scale data about human behavior. For example, this map shows where people are tweeting about sunrises over the course of a 24-hour period. There's a yellow flash of sunrise tweets whenever the sun rises above the horizon in a part of the world. You can see an interactive version of this map
- Social media sites like Twitter enable a lot of public discussion of the important issues of the day. But they also enable an even larger quantity of frivolous conversation. Last September was a good example. The nation was discussing two big topics: possible US involvement in a the war in Syria and Miley Cyrus's scandalous dance moves. In Washington DC, Syria conversations on Twitter were way more common than twerking conversations. But twerking was a more popular subject in most other states.
