I like that the landing screen clearly and boldly articulates what Guile is. I also really like the contribution page and the quick showcase of who uses it near the bottom of the landing page. I think the project has effectively focused the website on the most important information and demonstrates that a clean, modern look doesn’t need super fancy design tricks.
Again, I like the one-phrase description of what the project is. Here the landing page has a little more information and the top-level links are similar to Guile’s.
I don’t love the design but I think the content is a very useful model, especially the "about" and "get involved" sections.
Properties these share:
- Short, clear description of the project
- Single, well-considered top-level menu
- Clarity on how to get involved and how to edit the site itself
- White space, professional look (less true of the Nodejs one)
The QGIS site @wonderchook shared above also has many of these properties. Another nice thing about that one is that it is translated by the community in Transifex. It would be good to look at their tooling for that.
