	No adware or spyware guaranteed

Here is what masternewmedia.org says sets StumbleUpon apart from other Social Bookmarking services:

• Stumble Upon brings an exciting element of the (seemingly) random to your browsing experience, but retains all of the features of a traditional del.icio.us style social bookmarking service

 

• The Stumble Upon toolbar is really extensive, allowing you to find and rate bookmarks in a number of different ways without having to go to the Stumble Upon homepage

 

• Stumble Upon learns and adapts to your tastes over time, bringing you fresh recommendations you are more likely to be interested in without having to search for yourself
