An anonymous reader writes "Microsoft's Live Labs have introduced a new service that lets users collect snippets of information from Web sites and share the collections with others. It's similar in concept to Mozilla's Joey, a defunct project that let people copy and paste portions of Web pages onto a single page that they could access from their mobile phones or another computer. Thumbtack is also like other available services, including Google Notebook. But Thumbtack developers think their service has a difference. 'Thumbtack stands apart in its ability to introspect on incoming data in order to automatically classify it and extract structure from it using machine learning,' according to the FAQ about the service."
