James Hare on Wikipedia-L
I am pleased to announce a new project, WikiProject X, funded by a Wikimedia Foundation Individual Engagement Grant. WikiProject X's goal is to improve the experience of WikiProjects, which are subject-area (or goal-oriented) collaborative spaces on the English Wikipedia. post
By making WikiProjects easier to use and maintain, it will be easier to build sub-communities of like-minded people, giving editors a sense of community on a huge and daunting website like Wikipedia. This includes mechanisms for recruiting new participants and encouraging the creation of safe spaces where editors, new and experienced alike, can feel like they can participate in discussions without fear of intimidation or jargon.

WikiProjects provide some inspiration for this wiki's notion of neighborhood. My hope would be that the neighborhood would emerge for the activity rather than the activity being the product of the project.
