Adam, for the love of all that is holy, quit changing your signature back to this format. It stretches the page to the point that posts are unreadable.
I'm guessing it's the FitzGerald banner? I only edited it once (and that was to make it smaller than it initially was), but I'll see if I can crop or resize it some more without distorting it.
On my screen, you don't stretch the width of the page, but you do have an unnecessarily long signature that has an incredibly un-profound quote that took little cleverness or creativity to say or write.
