I was about to comment about this specifically until I saw that someone else beat me to it. THIS ARTICLE IS FROM 2005 PEOPLE

Sure, some things will have not changed, but I imagine a great many things will have. While its a good article and a good read, I wouldn't consider it up to date; if anyone has a more recent discussion I'd definitely be interested in reading it. For example, how the discussion covers largely RedHat based distros, if the article was written nowadays I think that would change.
