Linux for the common man

I guess I would start with RedHat.
It is available both as a retail package, and as a free download.

Then, I would visit a bunch of Linux resource sites.

Start by subscribeing to the Linux TechMail here at Tech Republic.

And, search the article archives for a wealth of links to web sites.

Don't neglect books either.
I recommend O'Reilly publishing.

Web sites that I have bookmarked include:
www.linuxorbit.com
www.dukeofurl.org
http://gcc.gnu.org
http://doc.kde.org
www.linuxdoc.org
www.linuxgazette.org
www.lpi.org
www.linuxbase.org
www.linuxdevices.com
www.bhami.com/rosetta
www.unitedlinux.com
www.virtual-linux.org

than the earlier ones. I would pick up Red Hat as it's the most prevalent, but SUSE and others are good. Personally, I think everyone should get over the distro-centric approach and one way to do this is to get several along the way. A lot of peoplecollect distros and then learn to pick and choose whatever they want.

Another thing, BSD is something I would definately look into if I was "looking at the market" right now. :)
