Question and Answer Platforms



Question & Answer Platforms
Question and Answer (Q&A) websites, platforms, and apps are also known as online knowledge markets. Both the questions and answers are crowdsourced. They allow knowledge seekers to connect with those who have the knowledge about a particular topic. The first example of an online knowledge marketplace was Usenet , which was created by two Duke University graduate students in 1980. It consisted of a bulletin board system where discussions were threaded. It was a distributed conversation where users connected to each other using various servers. Users posted questions and other users posted answers using their own knowledge. At first these Q&A platforms were confined to online websites only accessible to PCs. Today, they can be accessed anywhere at anytime by PCs, mobile phones, and personal tablets.

Below are several examples of both PC and mobile based Q&A applications. Additional examples can be found here.
