StumbleUpon is a search engine that recommends and directs users to webpages. Users create an account and choose "interests." Users are guided to webpages that have content relevant to their "interests." StumbleUpon allows users to find photos, videos, and other online content that they would not normally see.
Unlike many social media platforms, the primary objective of StumbleUpon is not to interact with other users. Instead, users interact with the site: choosing interests, giving feedback on suggested websites, and occasionally viewing trending webpages. The only time that interaction between users does occur is through Facebook. Users can invite friends from Facebook to join StumbleUpon. Additionally, users can follow other users in addition to their "interests."
