Don't know who is Kate? What is Kate's party? Well it started as a birthday party from a lady on Facebook. She accidently hasn't set the privacy settings as "private". Now over 60,000 people are attending and over 170,000 awaiting confirmation. Its like a viral and doesnt seem to stop any sooner. People on Facebook are creating endless groups too. Here are some of them.
