Rate my WebApp: FAQoverflow (www.faqoverflow.com)
https://news.ycombinator.com/item?id=1729166FAQoverflow is the coffee table book version of the Stack Overflow family of Q&A websites.
I wrote a Ruby Script that spiders the API to find the top 1000 questions on each of the 25+ sites, and which selects the best questions according to a quality heuristic before bucketing them into sections. The whole thing is published as a static site to S3/CloudFront and updated a couple of times a week. More technical details regarding implementation on the site itself.
The idea is to provide a nice, clean interface for browsing great answers to questions about everything.
