Pinterest is a platform for sharing visual content, primarily photos and links to recipes or ideas. Pinterest users can “pin” (pinning is a feature that makes a pinned post available on the user’s profile page and in search results) items to their boards, which are collections of related pins.
Pinterest users can also follow other users, who then receive notification when the user pins or shares an item.
Some people consider Pinterest a blogging platform because it allows users to create and share long-form content with a visual emphasis. Other bloggers consider Pinterest to be a visual cataloging tool that helps them organize their ideas and find inspiration for new posts.
Ultimately, whether or not Pinterest is considered a blogging platform depends on the individual perspective.
