Sometimes, we forget birthdays… (Image Credit: Someecards.com)

Last Tuesday, Slate’s editor David Plotz wrote about a social experiment he performed last July.

I was born on Jan. 31, but I’ve always wanted a summer birthday. I set my Facebook birthday for Monday, July 11. Then, after July 11, I reset it for Monday, July 25. Then I reset it again for Thursday, July 28. Facebook doesn’t verify your birthday, and doesn’t block you from commemorating it over and over again. If you were a true egomaniac, you could celebrate your Facebook birthday every day. (You say it’s your birthday? It’s my birthday too!)

Plotz’s Facebook wall was filled by well-wishers on all three of his “birthdays.” He writes,

My social network was clearly sick of me. I received only 71 birthday wishes on July 28, down from more than 100 on my first two fake birthdays. And even more skeptics caught on to the experiment: 16 doubters, compared with 9 from three days earlier.
