Social network aggregation

Social network aggregation is the process of collecting content from multiple social network services, such as Instagram, Tumblr, Flickr, LinkedIn, Vimeo, YouTube, etc into one unified presentation. The task is often performed by a social network aggregator (such as Rime), which pulls together information into a single location, or helps a user consolidate multiple social networking profiles into one profile. Various aggregation services provide tools or widgets to allow users to consolidate messages, track friends, combine bookmarks, search across multiple social networking sites, read RSS feeds for multiple social networks, see when their name is mentioned on various sites, access their profiles from a single interface, provide "lifestreams", etc. Social network aggregation services attempt to organize or simplify a user's social networking experience, although the idea has been satirized by the concept of a "social network aggregator."

There are other related uses of social media aggregators aside from simplifying the user's social networking experiences. Some aggregators (such as Juicer) are designed to help companies (and bloggers) improve engagement with their brand(s) by creating aggregated social streams that can be embedded into an existing website and customized to look visually intrinsic to the site. This allows potential customers to interact with all the social media posts maintained by the brand without requiring them to jump from site to site. This has the benefit of keeping customers on the brand's site for a longer period of time (increasing "time on site" metrics).

Social network aggregators

Social network aggregation platforms allow social-network members to share social-network activities like Twitter, YouTube, Stumbleupon, Digg, Delicious, with other major platforms. All content appears in real time to other members who subscribe to a particular community, which eliminates the need to jump from one social media network to another, trying to keep an eye on one's interests.

Social network aggregation systems can rely on initiation by publishers or by readers. In the publisher-initiated aggregation systems, the publishers combine their own identities, which make their readers see all aggregated content once subscribed. In the reader-initiated systems (such as Windows Phone 7 people hub and Linked Internet UI,) the readers combine the identities of others, which has no impact to the publishers or other readers. The publishers can still keep separate identities for different readers.

Technically, the aggregation is enabled by APIs provided by social networks. For the API to access a user's actions from another platform, the user will have to give permission to the social-aggregation platform, by specifying user-id and password of the social media to be syndicated. This concept resembles open id. In March 2008, The Economist reported that social network services are only beginning the move away from "walled gardens" to more open architectures. Some sites are working together on a "data portability workgroup", while others are focusing on a single sign-on system called OpenID to allow users to log on across multiple sites. Historically the trend from private services to more open ones can be seen across many Internet services from email and instant messaging to the move that early online service providers made to become websites. The OpenSocial initiative aims to bridge the member overlap between various online social network services.

Overlap between multiple social-network services

The attraction of social network aggregation comes from the fact that some users tend to use multiple social networks: they have accounts on several social-networking sites. In November 2007, Alex Patriquin of Compete.com reported on the member overlap between various online social network services:

Site	Bebo	Facebook	Friendster	Hi5	LinkedIn	MySpace	Ning	Orkut	Plaxo
Bebo	100	25	2	3	1	65	1	0	0
Facebook	4	100	2	2	2	64	1	1	9
Friendster	5	23	100	4	6	49	2	1	0
Hi5	7	24	4	100	1	69	0	2	0
LinkedIn	4	42	8	2	100	32	8	3	3
MySpace	3	20	1	1	0	100	0	0	0
Ning	6	35	6	1	19	44	100	2	2
Orkut	3	26	4	7	8	29	2	100	1
Plaxo	5	48	8	2	54	34	14	4	100

A 2009 study of 11,000 users reported that the majority of MySpace, LinkedIn, and Twitter users also have Facebook accounts.

Social networks as source of financial news

Social information is now as powerful as proprietary data feeds. Today social networks are more than the space to communicate and share ideas, it became the information source that can rock financial markets. Twitter alone provides an enormous opportunity for investors and traders:

• After Elon Musk tweet about new product line Tesla shares leaped by 4% ($ 1 billion of its market capitalization)
• On August 13, 2013 Carl Icahn tweets about his large stake in Apple Inc. He claims that the company is extremely undervalued and adds that he urges CEO Tim Cook for a larger share buyback. As a result, Apple shares surged 5% by the end of close on this day. This allowed AAPL stock to cross a key psychological resistance of $500.

In this way we can observe appearance of financial news aggregator, which gather information all around social networks, filter it and sort out by key topics. An example of such aggregators is UK-based start-up CityFALCON.
