Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 157 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I'm giving a presentation on social media with a short part based on Stack Overflow. How would you describe its key principles? What are its key benefits over the traditional forum/mailing list problem resolution?

This question came from our site for professional and enthusiast programmers.

This will probably be moved to One key feature of stackoverflow is that you do not talk about stackoverflow on stackoverflow. – magnifico Mar 29 '10 at 14:43
I'd have to agree with magnifico – David Antaramian Mar 29 '10 at 14:45
It doesn't have principles, it's all chaos built upon a phpBB framework. – random Mar 29 '10 at 15:32
Stack Overflow is just Jon Skeet's realtime brain dump – DVK Mar 30 '10 at 19:42
  • Focus on Q&A over discussion (keeps individual threads targeted at individual problems, makes them easier to find later)

  • Searchable/organizable via meta-data (tags + titles allow fast & effective filtering of search results)

  • Community editable (reduces the problem of new users abusing meta-data, allows incremental improvement)

  • Ranked answers (good answers posted after poor ones can still "float to the top" vs. lost in the noise of a traditional forum / list)

Jeff Atwood gave an excellent talk about Stack Overflow at EclipseCon 2009 that covered a lot of the bases and design rationale, including how certain features were inspired by MMOs :)

Let me try and dig up the link.
