Bill Hobbs rightfully laments the fact that a "real journalist" referred to his blog writings but didn't provide his readers a link to Bill's original material, or even a name for the source he was citing and criticizing.
Yes, that's lame. Not only is it standard operating procedure to cite sources, but it's good form.
There are only a few reasons why a writer wouldn't want to cite a source, and none of them are very flattering. Either the writer is trying to deceive his readers, or he is supremely arrogant. (Silence, Candace.)
However, Bill shouldn't get discouraged. This current crop of journalists is a dying breed; all the journalists and writers of the future are probably maintaining blogs of their own at this very moment.
