I enjoyed the article. Like others I have been in the Windows world for a very long time, and Linux is something of a new adventure for me. I just finished, with a lot of help from my friends, a RedHat 17 based NAS for my home network.

I am interested in the "WHAT" of Hadoop. As in what would it be used for in business? Would you or someone give some hard examples of uses?
