Developing and Promoting Social Network Applications: Rules of thumb

Some rules of thumb from Context Optional:

F: Frictionless: simple, less is more
A: Audience: on facebook for their friends
C: Communication: integrate into the viral channel
E: Engagement: hook users to return regularly. If you're not engaging users, they will go away.
B: Business model: design with monetization in mind
O: Objective: establish goals and success metrics
O: Obvious: make each page's purpose clear. Don't create about page, it has no value.
K: Keep working: develop, test, repeat. Viral is incremental.
