Your reputation is critical, be active in managing it!
CoderTribe can help you understand how people see you and your skills. It gives you a place to publically show, and deomnstrate your skills. As a registered member of CoderTribe you can add references to your work, integrate the social networks and communities you belong to, and participate in projects that impact your reputation.
You have the ability to review your score and get advice on ways to improve it. Want to be a Web 2.0 rock star? Build up your javascript or Ajax skills. Participate in projects that leverage these skills or contribute to open-source projects like Dojo or Ext. You don't have to do everything in CoderTribe for it to help.
More importantly, help us make CoderTribe a better place for you!
