Collaborations between open source projects and designers are difficult. Instead of focussing on a lack of tools or skills, I want to show that the difficulties are also rooted in different views on what makes a "good" user and a desireable mode of collaboration. Open Source projects, prototypically, focus on the developer/user who scratches an own itch and coordinates in an stigmergic, bazaar-like way, while design usually focusses on expertise in designing for others and a plan/execution model instead. While no easy fix can resolve these differences, I want to suggest some ways to ease communication for developers and designers.
