Googling to troubleshoot Linux sucks. Part of the suck is that Google's page rank favors old pages. Part of it sucks because it's keyword finding favors forum threads where the terms are in someone's signature.
And part of the suck isn't Google's fault because GNU/Linux documentation is dense to the point of opacity. It is great for professional standings and not so great for amateur ones.
Worst of all is that FOSS documentation has a lot of "not my problem" links. If a piece of Software is doing something bad to Firefox it's documentation will mention Firefox and link to the Mozilla homepage...so to speak.
