Reputation and point system models

Question

I'm looking to implement a reputation-based point system for a QA site. I like Stack Overflow's model, but I was wondering if there's anything else like this out there. I was doing some research on the web, but couldn't find a good compiled list of reputation models. If there's a study of reputation models with pros and cons, that would be super valuable.

Answer 1

O'Reilly and Associates actually has a blog and a book coming out about this.

As far as 'systems', there are many:

• Reddit
• Slashdot
• Digg
• Wikipedia (Implicit with Trusted editors)
• Ebay

Among many, many others.

For a related but different approach, check out http://www.klout.com - they're building a web-wide reputation system that looks at social signals from a growing list of sites.
