StumbleUpon
Updated: 10/07/2019 by Computer Hope
StumbleUpon was a great free website that allowed users to rate a site they like or don't like by clicking a thumbs up or thumbs down icon.
Users could use a free add-on, available through the company's website to rate pages as they browsed and visit other users' pages and view their "Stumblers" — items on the Internet they've found interesting.
On June 30, 2018, StumbleUpon became part of Mix, a social and sematic personalized platform that builds on the StumbleUpon foundation.
