Publishing — In media production and publishing, content is information and experiences that may provide value for an end-user/audience in specific contexts.[1] Content may be delivered via any medium such as the internet, television, and audio CDs, as well as live events such as conferences and stage performances. The word is used to identify and quantify various formats and genres of information as manageable value-adding components of useful media to the target audience.

Curation tools are now not only limited to bookmarking functionality but it is expanding the turf into other areas, like publishing, education learning, contents social network and many others related to contents and knowledge.

Many research has been done on user behavior related to social acidity. Based on principal media rules

In Internet culture, the 1% rule is a rule of thumb pertaining to participation in an internet community, stating that only 1% of the users of a website actively create new content, while the other 99% of the participants only lurk.

A variant is the “90–9–1 principle” (sometimes also presented as the 89:10:1 ratio),[1] which states that in a collaborative website such as a wiki, 90% of the participants of a community only view content, 9% of the participants edit content, and 1% of the participants actively create new content.

Both can be compared with the similar rules known to information science, such as the 80/20 rule known as the Pareto principle, that 20 percent of a group will produce 80 percent of the activity, however the activity may be defined.

With good work flow, contents, community activity, content curation site may give huge value for people as the contents are really filtered by human based on real people interest. This will create others values, like trending, values and interaction.

With this people are starting flocking to the sites to engage and consume contents. Building contents champion in each area are to be encourage.
