I think plagiarism accusations are frequently a bit of a stretch. 700 word columns can't have the citation standards of an academic paper, and while people deserve criticism for being a bit sloppy it doesn't mean they have committed the high crime of plagiarism (and part of the problem is that there seems to be this Plagiarist/Not A Plagiarist duality, when of course there are grey areas).
But this is basically a C&P job.
