It's ok, it isn't meant for you.

I also didn't get it, and I worked very closely with Danielle for a long time at Twilio. Then one day my sister-in-law who writes a blog about her hobby farm and Etsy business IMed me and asked "how do I make money from my blog?" She's tech savvy, but the idea of an affiliate network is outside her realm of understanding. I sent her to refer.ly and she instantly got it. That's the sweet spot. It's not me or you.
