The Linux guru (or guru wanna-be) should bookmark this site. Linux is UNIX freeware available for Intel's x86, Motorola's 680x0, DECS's Alpha CPU and Sun's sun4c and sun4m machines, and is currently being ported to the PowerPC architecture. This meta-site contains documentation in many different languages, links to a great number of applications and utilities that run on Linux, user groups world-wide and other topics of interest. So, whether your question concerns the latest version (2.0.27) or the difference between various distributions, or if you've decided to write the next kernel, this site is a natural place to start.
