I've always liked the way the Cultural Anthropology journal website has the "area" and "theme" lists. These have been really helpful for students, especially, navigating the vast cache of articles. For each project, the salient categories might be different (other than, or in addition to areas and themes) but having a small number of ways to slice through the material, like having just a few primary tags that enable curation, could be an overall approach that could adapt to different projects. This could help with the public facing elements of projects, but also be useful for researchers, especially people that are relatively new to the project and exploring the content.
As a splash page, it would be great to have features that make this page splashy :) This would include a focus on ease of working with images, perhaps with a visual essay-type format. We could have captions when you mouse-over the images. For some projects it could be good to have an intro video, a bit like Kickstarter, that serves to provide a compelling overview and help people see how they can get involved. I know this feedback might be a bit more content focused than /features/ per se... Institution, funding agency, etc. could still be included by could be moved down a bit so the first elements the user sees are a bit more inviting and attention grabbing.
