Formspring
Formspring was a social networking service that allowed users to ask and answer questions anonymously or with their identity revealed. It was launched in November 2009 and gained popularity in early 2010. The platform was designed for individuals to connect with one another through a question-and-answer format. Users could create profile pages, follow other users, post questions, and receive answers. In 2013, Formspring announced that it would be shutting down due to financial difficulties.
