Congrats on cutting your 700 words! If that made your story tighter without losing what you wanted to express, I'd say the exercise was time well spent. (Ha! I stopped myself from saying "definitely time well spent", in light of the article's advice.)
Mostly when I read blog articles like that I keep in mind that the blog author's goal is to increase hits to his/her site, therefore, content that is opinionated enough to get bookmarked and discussed, ie. to bring in more page views, is good. Could the author have cut a bunch of flab from that overly long list of phrases and made his post more readable, yet less bookmarkable? .... Uh, yeah.
