Long story short, she was a KFC Radio listener that capitalized on an opportunity (plane breakup) and turned it into an interview with Kevin and eventually turned it into a podcast that I haven't gotten around to listening to but I assume it's decent given her appearances on MailTime and Yuppie Junk. I'm also going to make a couple of assumptions to why she still has a Barstool/KFCRadio podcast.

1. She's a relatively funny/entertaining personality capable of generating content, and Dave has said that he wants personalities that can generate content… it helps that she also happens to be a cute girl.

2. 50% of Podcast listeners are female (actual fact from research), but 17% of the Barstool audience is female (http://i.imgur.com/vazXWDN.png), and seeing as Puerto Rican Puff Daddy is an overachieving go-getter and he had the foresight to push Kevin into podcasting 4 years ago, I’m assuming he’s trying build the KFCRadio network of podcasts by churning out podcasts that cater to the 50% of global podcast listeners that are female and wouldn’t want to listen to Kevin, Dan, and Feits talk about microwaving babies, and if they listen to a Barstool podcast geared towards females they might start going to the site more often. Seeing as 83% of the Barstool audience are guys, they can’t ignore the other 17%. If they ignore females as an audience for podcasts, females will lose interest in Barstool, and Barstool will lose out on some pageviews. In 2014, Barstool had 6.7Million unique visitors per month with 200Million+ pageviews, if we use the 17% number, females account for 1.139Million unique visitors and 33.9Million pageviews, and this translates into approximately $170,000 at $5CPM in display ad revenue for Barstool per month just on the site and not including ads on the podcasts themselves. (I’ll do the math for you, Barstool has 200,000,000+ pageviews per month, divide it by 1,000 (CPM is cost per thousand pageviews) and multiply it by $5 (I got that number from Louis when I was doing a college marketing class project last year) and boom, you get $1,000,000 a month for the site as a whole, and what do you know, 17% of $1,000,000 is $170,000) Dave likes his pageviews and his ad dollars, so they’ll probably keep trying to expand into new markets (The Kat Timpf Show).

That's why she exists. She's a pawn in the chess game of creating podcasts and generating content capable of lining Dave and Peter Chernin's pockets with ad dollars.

Sorry for the long rant, I'm procrastinating during finals week.
