Here's some things I'd like to have on the compass website eventually, some of this is vaporware, but it won't be soon enough:
1. Homepage - value proposition, overview video, links to key resources, etc
2. Sass Language reference
3. Compass tutorials/videos
4. Framework references and tutorials
5. Plugin Directory
6. Lab - type sass and get css, use compass mixins. try before you buy.
7. Pixelations - This is a sass-based picture drawing tool that I've made but not yet released. It's pretty ridiculous, but fun. Create, save, and share your pictures as sass files and watch them update in real time.
8. Credits - links to author homepages, donors of time and resources to the compass project, etc.
9. View the styles of the site
10. Website directory - Links to sites that are built on compass.
As far as visual design goes, I'd like to convey clean, simple, slightly technical. Designers will be looking at this site and as a first impression, will judge the quality of the tool by the design.
The website should be a model of how to put compass and sass into practice. Clean semantic html, modular sass files, use of compass mixins, etc.
I'm happy to start with the home page now, but I thought I'd give my vision for the total site content first.
