From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I do it because I can... I read release notes on every update and once you've configured a kernel for a particular machine you really don't need to touch the config, barring major changes like when PATA and SATA merged. Or of course if I'm adding a new piece of hardware.
I remove everything I don't need and compiling the kernel only takes a couple minutes. I use Gentoo and approach everything on my system the same way - remove the things I don't need to make it as minimal as possible.
Compiling your own kernel also makes it easier when you need to do a git bisect to determine when a bug was introduced to report it or try to fix it. I've also included kernel patches in my build years ago, but haven't needed to do that in a long time.
I used to compile a custom kernel for my phone to enable modules/drivers that weren't included by default by the maintainer.
It's not about performance for me, it's about control.
