When we understand the value of the social media network effect, we would think twice before we reject the idea. Social media enables far reach of many more audience than classical media for a fraction of the costs.
Network effect
Figure 1: Telephone network performance (derived from Wikipedia network effect article, 2008)
When social Web users incrementally collaborate and exchange experience using a specific social platform, interest increases. The useful and informative content attract new users and lead to more engagement from current ones. The increased platform usage leads to more interesting content. The platform will be more attractive and so on.
"A product displays positive network effects when more usage of the product by any user increases the product's value for other users (and sometimes all users)" (Arun Sundararajan, 2006).
This network effect can be illustrated by a telephone network. The increasing number of telephones leads to more value of existing telephones.
Network effect In Action
The "World of Warcraft" (WoW) game is a good example of how the network effect can positively increases players' performance through exchanging information and experiences. New players learn from their peers experience shared in forums, blogs, Wikis and high quality answers and instructional videos.
"The more players participate and interact with WoW's knowledge economy, the more valuable its resources become, and the faster players increase their rate of performance improvement. Said more generally, the more participants--and interactions between those participants--you add to a carefully designed and nurtured environment, the more the rate of performance improvement goes up "(John Hagel III et al., 2009)The figure below presents performance of WOW new players. After the first 150 playing hours, players win on average two million points. After the next 150 hours they can win eight million points, though the next levels are more difficult.

In subsequent posts, I will present more practical applications of social media to extend (and not replace) the classical marketing and PR methods.
