Yay, I get to be a Grammar snob! This article needs to be edited. There are a couple if not more places in it where the gender pronoun is changed nonsensically from "her ..." to "his ...". It makes the article feel like it was run through an article spinner or obtained from one.
I would think that Oprah would want to be represented by people who knew the value of Grammar. That said the spellings were great. But spelling is not grammar. Grammar is the proper use of a word in its context. Plus the proper use of Punctuation. And unlike what I'm doing here, the proper use of capitalization among other things. It's the big brother to spelling, basically it's sentence and paragraph spelling.

I don't expect comments to ever follow Grammar but I do expect articles to do so.
