iLeonardo (not to be confused with anything from Apple) is a social utility that connects people and their collections of information on the Web. It's part shared bookmarking and social network, and part of the growing number of Web sites that are leveraging the wisdom of the community.
Introduced at Demo 08, iLeonardo collection repository is called a Notebook. Users can drag and drop links and content into a notebook, and share these collections with friends and contribute to public collections of notebooks. The social aspect is being able to discover relevant content in other notebooks and to receive news feeds on activities in Notebooks from people you connect with on the service. "You get the benefit of other peoples' research," said CEO Joshua Rosen.
iLeonardo users maintain a profile that includes profile data, preferences, recent actions, and Notebooks. The service lets users select who can view their information.
iLeonardo is in private beta and will support itself with ad placements, Rosen said.
