Abstract Patatte is a simple social network that helps people to find and collaborate with informal and semi-formal experts. This project’s aim is to solve the ‘expert finding+ problem’ which is the problem of finding an unknown expert (for any purpose including hiring, working with or questioning the expert) by searching through real world or online social networks with skill or interest keywords. The system is designed to be simple and intuitive to use. This is because some of the targeted users (informal and semi-formal experts) are basically educated and may have limited experience with the usage of web applications and social networks. The system is also accessible by the most basic internet user requiring a computer, internet access and a basic knowledge of how to use social networks. Users can share projects they have worked on, follow other users, view those users’ projects, like some of those projects, search for users with specific skills and collaborate with them in an integrated media sharing and chat application.
