StumbleUpon (from the English. "Randomly found") is a commercial web page search service that combines the principles of p2p and social networking with one-click blogging . The free web browser toolbar provided by the system automates the collection, distribution, and reviewing of web content within an informal social structure, giving users a way to view, similar to switching television channels.

StumbleUpon combines a collection of human opinions with machine learning to personal preferences and creates virtual communities of like-minded web surfers . Estimated sites are entered into a personal profile (blog) and spawn surfer networks united by common interests. These social networks coordinate the distribution of web content, so users “stumble” on pages recommended by their friends and peers. Such collaborative content research automates the sharing of tips and simplifies network navigation.
Stamblers (as community members call themselves) also have the opportunity to evaluate and review each other's blogs, to unite in interest groups, which are collective blogs with a given topic. There, users can post comments and links to the stated subject as in the web forums.
StumbleUpon uses a database of personal user preferences for targeted advertising. A small number of “finds” - usually less than 2% - are sponsor pages that are selected according to the user's interests (if the user frequently visits the photo sites, then advertised sites associated with photos will sometimes be shown to him). Pre-advertised sites are checked by the person for quality and relevance. By paying for raising the status of your account to "sponsor", the user can disable advertising for a certain time.
StumbleUpon is not spyware , and information is transmitted to the server only because of an explicit user choice, information such as the addresses of all visited sites (including those not in the database), the time they are marked, and profile settings are stored on the server and, partially, locally. .
