TechNadu: StumbleUpon Alternatives that still work in 2019 (and reason for its shutdown). “In 2018, StumbleUpon, our favorite content curator on the internet, stopped its services forever after being active for straight 16 years. Many think it’s the result for being inadaptive to the new generation social media trends. The website was stale and irresponsive on mobile. Often the content from the other site didn’t support its interface. It was time for a change. Now, upon visiting the StumbleUpon’s website, it redirects the user to a new website mix.com, which also, at the moment, is our top StumbleUpon alternative. After its exit, many of StumbleUpon’s alternatives came into the scene to organize your various interests at one place. Here, we are listing our top 10 alternatives of StumbleUpon.” Some standards here (Reddit, Digg) and some you may not have heard of.
