Establishing an effective Wiki normally requires an active community of contributors. The Viral pattern can lead to a rapid explosion in the number of users, but it is often difficult to generate a “critical mass” that ignites such an explosion. Without such a critical mass, the Wiki will often fall into dis-use.

There are two main aspects to attaining critical mass:

1. Content
   • There needs to be a substantial amount of compelling information that causes people to want to return to the site and tell their friends to join as well.
   • Some document repositories can (or should) be wiki-fied. Conversion of those documents would provide both a source of content and contributors who have a stake in the wiki.
   • Encourage people to contribute in small chunks, by implementing the “1-minute” model (take no more than 1 minute to write down an idea, suggestion or information and add it to the wiki.)

2. Contributors
   • There needs to be a substantial number of users so that newcomers can feel part of a community.
   • There needs to be some key people who are respected and active contributors.
   • One approach in a commercial context is to make Wiki participation part of people's job. For instance, a Services Manager may tell their Consultants that they are expected/encouraged/allowed to spend one hour each week writing up notes on their clients in a CRM (Customer Relationship Management) Wiki.
   • Maintaining a strong Community Portal can be key to encouraging participation. If people don't know what needs doing, they are prone to look around a little and then leave. If there's a clear list of things that could be accomplished they are more likely to adopt one of the tasks as their own.
