I was indifferent towards her up until... 2005, I think... she decided to abuse her power to harass a business owner whose employees wouldn't let her into the building because it had stopped allowing new customers inside fifteen minutes prior to her arrival. I mean, that's common policy for most businesses. When you're closing, you don't suddenly kick everyone out, but you also don't let anyone else in. The owner (whose business was now being actively boycotted by Oprah's fans) even had to go onto the show, apologize for his staff doing their jobs properly, and give her the overpriced purse (which I'm sure she desperately needed THAT day) for free.
Seeing this piece and learning about her fans flipping out over a harmless slip and fall doesn't surprise me in the least. I'm just glad she didn't decide to stand in front of a camera the next day and start blasting the manufacturers of her shoes for it while demanding a face-to-face apology in front of a live audience.
