Lampcms is an full-featured Open Source Question and Answers web program with deep integration with Facebook, Twitter, Tumblr and Blogger and soon LinkedIn APIs
Question/Answer websites are becoming very popular, many people find them to be a better choice for building online communities than a traditional web forum.
Just like many other Question and Answer sites, Lampcms is tag-based, meaning there is no need to create separate forum for separate topics, all questions are tagged by the author and can then be grouped by tag.
Some prominent programmers have been referring to LampCMS as an Open Source StackOverflow and Quora crossover. All we can say is there are certainly several features similar to those of StackOverflowand several similar to Quora but this program also has some features similar traditionally found in popular Forum Software like “Sticky threads” and “Dot folders”
