Paste is a pasteboard/pinboard running on the social networking platform pnut.io, at paste.mcdemarco.net. Each paste has a public link that can be viewed without logging in to pnut.io, as well as a "private" link for use by other pnut.io users and apps. Logged-in users will also see a list of their recent pastes. To create pastes, you will need a (free) pnut.io account.
Pastes require a description; a default description is provided for you. Pastes may also have titles, paste text, a type for the paste text (used for display and highlighting of the paste text), and hashtags in the description.
