It’s worth reiterating that the CDG probably isn’t intended for casual, non-scientific users. However, the bigger problem from a user interface viewpoint is the fact that it can’t seem to decide whether it’s intended for frequent users.
As a result, it has an ongoing identity crisis about how accessible it wants to be, and how easily it wants to allow users to provide input and new content.
Based on those factors, we’d suggest posting a YouTube tutorial right up front, to help walk through a variety of problematic user populations: casual users, non-web-savvy ecological science folks, and first-time users.
This would also have the benefit of showing off the various features of the site, and provide a more immediate multimedia presence on the front page than the existing slide show.
