A few weeks ago Kelly Wearstler was brought up on list regarding Playboy centerfolds. An argument was taking place on her talk page between two users - one an advocate for using the Playboy infobox with chest size as the infobox for Wearstler, a world famous fashion and interior designer (to be honest, I had no clue who she was until I researched her, heh). I snuck in and added a normal biographical infobox and Wikipedians proved the Playboy user wrong - he had declared that the only information he could find online was content about her being a Playboy model (which she posed for once, as a centerfold, to pay off her student loans and start her own business).
Well, they were wrong (they must have been searching for her name and "Playboy")...and, now she's a DYK for her interior design, not her Playboyness ;)
I love that we can share interesting, not so interesting, or troublesome articles and fix them up and expand content. Just one of the reasons why this is my favorite list <3
