About 6 years, since 2006 when it was version 2.2.
I'm a WordPress developer. Sometimes I do design, but primarily, a developer.
I'd like to learn about the core architecture of WordPress. Another thing I'd like to learn is how to optimize WordPress in a large scale, like WordPress.com.
Settings API, how to write a plugin, HTTP API, etc.
