I am looking for open source code bases of web sites that developers can learn from, inspiring sites that get everything right.
In particular, a site should excel in all these areas:
- Consistently fast load speed
- Semantic HTML
- Seperations of concerns (Data/HTML/CSS/JS)
- Accessible
- RESTful
- Gracefully degrades / Progressive enhancements
- Appropriate HTTP headers, including caching
- Secure
These websites should be open source and the code should be hosted somewhere.
