I Want to know if it is any here that helps devolop Linux??

There are a lot of parts to Linux, including applications that are not necessarily dependent upon the operating system. So, do you mean the kernel, LSB (Linux Standard Base - includes the kernel), desktop managers (not tied to Linux), development tools (GNU compilers, Java, Perl, Eclipse et al are also not tied to Linux), X-Windows (ditto), database managers (MySQL, Postgres, et al - ditto), media players and tools (VLC, mplayer, ffmpeg - ditto)... Please be specific. That said, I have submitted bug fixes to open source projects, which is what Linux systems are mostly composed of. The Linux-specific parts are actually quite small and mostly developed and maintained by a dedicated group of people. Those things would be the kernel, device drivers, file systems, and such. Most of the parts that users see are not specifically Linux, but work with Linux and may well have been developed to run on Linux, but are likely only dependent upon the development tools used - GNU compilers and libraries, or X-Windows for the most part, so they can be ported fairly easily to any system that supports those tools, which include Unix of may flavors, Windows, OSX, QNX, and more.

I mean The Kernel :P Not GNU

Well, there are people who work on the kernel - go to www.kernel.org for more information. There are people who report bugs, fix bugs, etc. and submit them to the kernel development team. Then there are those that create loadable kernel modules such as device drivers and such. I fit into the latter category. While I work on modules that extend or enhance the kernel, I don't work on the kernel, per se. So, if your question is whether or not anyone here works directly as part of the kernel development team, well the same organization that supports kernel development, the Linux Foundation, has purchased this organization (Linux.com) and is working on a new, improved web site which should be going public "real soon now".
