Tantaran'ny tamba-jotra ara-piaraha-monina
Efa tamin'ny taona 1978 no namelabelaran'i S. Roxanne Hiltz sy Murray Turoff tao amin'ny bokiny The Network Nation(Addison-Wesley, 1978, 1993) ny momba ny fampifandraisana ny isam-batan'olona amin'ny alalan'ny solosaina.

Anisan'ny voalohany tamin'ireny tamba-jotra ireny ny Classmates.com (1995), izay nampifandray  ny mpiara-mianatra teo aloha tany Etazonia, sy ny SixDegrees.com (1997), izay nampifandray ny  tsy mifankahalala mivantana. Nisy karazany roa ireo tamba-jotra nipoitra tamin'ny 1999. Tao ireo  niankina tamin'ny fampifandraisana ny mpikambana mifampatoky toy ny Epinions.com, tao kosa ireo nifototra tamin'ny "finamanana" toy ireo naorin'i Jonathan Bishop araka izay voalzan'ny boky .. Ny zava-baovao tamin'izany dia tsy ny fampisehoana fotsiny ireo "mpinamana" fa ny famelana azy ireo hanolotra tahiry sy votoatiny araka izay tiany.

Heverina ho mihoatra ny 200 ny tamba-jotra ara-piaraha-monina.

Fampiharana amin'ny fiharian-karena sy ny orin'asa
Social networks connect people at low cost; this can be beneficial for entrepreneurs and small businesses looking to expand their contact base. These networks often act as a customer relationship management tool for companies selling products and services. Companies can also use social networks for advertising in the form of banners and text ads. Since businesses operate globally, social networks can make it easier to keep in touch with contacts around the world. In many ways business networking on social networks has eclipsed the amount of networking that takes place on dedicated business networking websites.

Fampiharana amin'ny fahasalamana
Social networks are beginning to be adopted by healthcare professionals as a means to manage institutional knowledge, disseminate peer to peer knowledge and to highlight individual physicians and institutions.  The advantage of using a dedicated medical social networking site is that all the members are screened against the state licensing board list of practitioners.

The role of social networks is especially of interest to pharmaceutical companies who spend approximately "32 percent of their marketing dollars" attempting to influence the opinion leaders of social networks.

Fitenenana sy fampiharana isam-pirenena
Various social networking sites have sprung up catering to different languages and countries. The popular site Facebook has been cloned for various countries and languages and some specializing in connecting students and faculty.

Tamba-jotra ampiharina amin'ny fiantrana olona
Several websites are beginning to tap into the power of the social networking model for social good. Such models may be highly successful for connecting otherwise fragmented industries and small organizations without the resources to reach a broader audience with interested and passionate users. Users benefit by interacting with a like minded community and finding a channel for their energy and giving.  Examples include SixDegrees.org (Kevin Bacon).

Firafitry ny tamba-jotra

Ny fampiasana fototra ny tamba-jotra
In general, social networking services, such as MySpace, Facebook and Bebo, allow users to create a profile for themselves. Users can upload a picture of themselves and can often be "friends" with other users. In most social networking services, both users must confirm that they are friends before they are linked. For example, if Alice lists Bob as a friend, then Bob would have to approve Alice's friend request before they are listed as friends. Some social networking sites have a "favorites" feature that does not need approval from the other user. Social networks usually have privacy controls that allows the user to choose who can view their profile or contact them, etc.

Fanitarana hafa eo amin'ny tamba-jotra
Some social networks have additional features, such as the ability to create groups that share common interests or affiliations, upload videos, and hold discussions in forums.  Geosocial networking co-opts internet mapping services to organize user participation around geographic features and their attributes.

Fomba fiharian-karena amin'ny tamba-jotra
Currently, almost no social networks charge money for membership.  In part, this may be because social networking is a relatively new service, and the value of using them has not been firmly established in customers' minds.  Instead, companies like MySpace and Facebook sell online advertising on their site. Some believe that the deeper information that the sites have on each user will allow much better targeted advertising than any other site can currently provide.  Sites are also seeking other ways to make money, such as by creating an online marketplace (Facebook's Marketplace) or by selling professional information and social connections to businesses: such as LinkedIn.

Olana eo amin'ny fiarovana ny tsiambaratelon'ny tsirairay
On large social networking services, there have been growing concerns about users giving out too much personal information and the threat of sexual predators. Users of these services need to be aware of  data theft or viruses. However, large services, such as MySpace, often work with law enforcement to try to prevent such incidents.

In addition, there is a perceived privacy threat in relation to placing too much personal information in the hands of large corporations or governmental bodies, allowing a profile to be produced on an individual's behavior on which decisions, detrimental to an individual, may be taken.

Furthermore, there is an issue over the control of data - information having been altered or removed by the user may in fact be retained and/or passed to 3rd parties. This danger was highlighted when the controversial social networking site Quechup harvested e-mail addresses from user's e-mail accounts for use in a spamming operation.

Fandalinana

Social network services are increasingly being ampiasaina in legal and criminal investigations. Information posted on sites such as MySpace and Facebook, has been ampiasaina by police and university officials to prosecute users of said sites. In some situations, content posted on MySpace has been ampiasaina in court to determine an appropriate sentence based on a defendant's attitude.

Facebook is increasingly being ampiasaina by school administrations and law enforcement agencies as a source of evidence against student users. The site, the number one online destination for college students, allows users to create profile pages with personal details. These pages can be viewed by other registered users from the same school which often include resident assistants and campus police who have signed-up for the service.
