I just made a Greasemonkey script a few minutes ago to alter the layout of the Linux.com website. The site layout actually prompted me to install Greasemonkey, as I'm using a 1680 resolution, and I wanted to make use of all of that screen real estate. Anyhow, the script I came up with is attached to this post and seems to work okay for me; it should stretch out everything to 100% of your monitor width. Hopefully I'm not doing anything stupid, as I never used Greasemonkey until about 10 minutes ago, so this is the first script I've ever attempted with it.
*Edit* Forum software won't let me attach a file with a .js extension, so I placed my script here: http://www.thelinuxpimp.com/files/linuxcom.user.js
