An Activity Stream is a digital record of activities performed by an individual on a particular website[2]. This concept was pioneered by Facebook[1] in 2006 through their News Feed feature. The primary objective of an Activity Stream is to foster interaction between websites, a goal pursued by projects such as the Activity Streams initiative. Today, major platforms like Facebook and MySpace[3] have opened their Activity Streams to developers, extending its usage beyond social networking to become an essential tool in business software for internal communication. There are two main types of Activity Streams: generic feeds that display the same content to all users, and personalized feeds that tailor content and rankings for each individual user. This function has been integrated into various business software, including enterprise social software like Jive Software, Yammer, and Chatter, as well as collaboration software providers like tibbr, Central Desktop, and Wrike. Notable implementations can be seen in offerings from Oracle, Salesforce, and Traction TeamPage. Activity Streams are also found on platforms such as LinkedIn[4], micro.blog[5], and Identi.ca, and were present on now-defunct platforms like MySpace, Diaspora, and Orkut.
An activity stream is a list of recent activities performed by an individual, typically on a single website. For example, Facebook's News Feed is an activity stream. Since the introduction of the News Feed on September 6, 2006, other major websites have introduced similar implementations for their own users. Since the proliferation of activity streams on websites, there have been calls to standardize the format so that websites could interact with a stream provided by another website. The Activity Streams project, for example, is an effort to develop an activity stream protocol to syndicate activities across social web applications. Several major websites with activity stream implementations have already opened up their activity streams to developers to use, including Facebook and MySpace.
Though activity stream arises from social networking, nowadays it has become an essential part of business software. Enterprise social software is used in different types of companies to organize their internal communication and acts as an addition to traditional corporate intranet. Collaboration software like Jive Software, Yammer, and Chatter offer activity stream as a separate product. At the same time other software providers such as tibbr, Central Desktop, and Wrike offer activity stream as an integrated part of their collaboration software solution.
Activity streams come in two different variations:
- Generic feeds: all users see the same content in the activity stream.
- Personalised feeds: each user gets bespoke items as well as custom ranking of each element in the feed.
