StumbleUpon is a commercial web search service that combines the principles of p2p and social networking with "one-click" blogging. The free toolbar for the web browser provided by the system automates the collection, dissemination and review of web content within an informal social structure, giving users a viewing method similar to switching TV channels.
StumbleUpon combines a set of human opinions with machine learning to personal preferences and creates virtual communities of like-minded web surfers. Valuated sites are recorded in a personal profile (blog) and generate networks of surfers united by common interests. These social networks coordinate the distribution of web content, so that users "stumble" on the pages recommended by their friends and "classmates." This collaborative content research automates the exchange of tips and simplifies network navigation.
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
