Stack Overflow - Programmer's Q & A Haven

What is Stack Overflow?
Stack Overflow is a web application written by collaborative programmers for programmers with programming questions. The site initially requires nothing when you first visit, but to be able to gain further editing privileges, then you must sign-in using a new or existing OpenID account. OpenID is a one-stop sign-in or sign-up account used to help ease the pain of remembering login names for different sites. Upon successfully registering for the site, you’ll be immediately given the ability to edit your personal account info, easily search for a question or answer (either by tags or textual search), and post questions or answers. Soon, after you make your first post, moderators, or users who have gained high reputation will rate the prevalence of your post given the appropriateness and popularity. You’ll be given points depending on these factors, which then will correspond to your abilities on the site. If you gain higher status in your reputation, then the site awards you the ability to edit yours and other’s posts almost like a wiki. At times you might feel that Stack Overflow is giving you a hard time, but it does it for good reasons. The most popular attraction of this site is its strict rules on postings. Since posters must stay on topic, the site’s reputation and purpose gets further established in the community. The simplicity and specificity gives Stack Overflow a name in the community of programmers as a “programming FAQ” site, rather than a sub-category amongst other contending search topics. Also, it helps eliminate the trouble of irrelevant or duplicate questions. In my opinion, this proves to be a good strategy than most other social networking sites that deal with a conglomerate set of topics, like Digg or SlashDot. Its unique moderation and rating system makes it an ideal example for newer social networking sites to follow.

What were my Stack Overflow experiences?
Stack Overflow is a "programmer's haven" for Q & A's. I have posted one question regarding the goods and bads of using more than one level nesting in Ruby on Rails. Hopefully, the question will get picked up by the community and I'll get an answer that will suit my needs.
Here's a direct link to the question: http://stackoverflow.com/questions/164520/to-nest-or-not-to-nest

Overall, I think the service will be a good addition for programmer related sites. I've definitely given this a good rating on my StumbleUpon and bookmarked it for future visits.
