I'm the WITCH, Ay. xD

My thoughts on why this blog succeeded:
 * It's an easy question that concerns everyone since everyone has a birthday.
 * It sparks people's curiosity. They want to know whether they share b-days with someone cool.
 * People are emotionally attached to the outcome. They want to share b-days with someone they like.
 * It's fool-proved due to the instructions. If I didn't provide the link and the instructions a lot of people wouldn't know how to find out and hence wouldn't have commented.

... *frowns* Damn! Why did I even analyse that? I guess this is what they call "habit of trade"...
