Ask and answer questions on your own Q&A site. While other Q&A websites are good for information sharing and communities, Qhub wants to offer a targeted community managed by the people that are interested in that particular subject area. Use a subdomain of qhub.com or your own hostname. The API supports question lists, asking questions and answering questions.
Successful Social web sites keep users engaged. One popular engagement feature is Questions and Answers (Q&A), where users can ask questions and experts (or any user) can answer. Qhub, a service that allows you to setup a Q&A section on your site has pushed the envelope by releasing its Qhub API that could enhance your Q&A offering in your application and increase its reach via applications.
