A search on "Content Security Policy" shows that Mike West's H5R article is the first item. As great as that is, the same search results show a publication date of June 2012. Yet the article was updated to include level 2 changes in May of last year.

Since this date is likely to make readers assume the article is inaccurate, we should change the posted publication date. (I don't remember how to do this, else I would change it myself.)
