Neowin: After 16 years, StumbleUpon finally retires to give way to Mix

Neowin: After 16 years, StumbleUpon finally retires to give way to Mix. “StumbleUpon used to be the discovery engine that pushed recommended sites to users prior to the social media age dominated by Facebook and Twitter. Its co-founder, Garrett Camp, announced in May that the content aggregator site would be shutting down by the end of June, and asked Stumblers to migrate their accounts to Mix.com. Over the weekend, the final hour for StumbleUpon has come to pass: the content discovery site has shut down 16 years after its launch.”
