That is good advice for IT folks who want to learn to admin a box, but for the average user it's actually very bad advice when Mandriva, SuSE, Ubuntu(/Kubuntu/nubuntu/etc_), Linspire, and many other distributions are very nearly plug & play - and are actually easier to set up than Windows.
Gentoo and Slackware is actually bad advice for the majority of casual users.
How to choose a distribution:
1. Query this messageboard for the "which linux" or "which distro" every newbie seems to ask (obviously without first searching)
2. Read the threads that come up (there are at minimum scores, more likely hundreds)
3. Check out distrowatch
4. Download several, try them
You are now an informed consumer. Pick one.
There isn't any possible "which distro" question you can ask which would make your particular question different from every single other person who has asked the same question here already.
