I'd never heard of this, but this thread reminded me to go check my Facebook.... and what is top of the the list in my newsfeed? Yep, this:
"Put ♥ this ♥ on ♥ your ♥ status ♥ if ♥ you ♥ know ♥ someone ♥ who ♥ has ♥ or ♥ had ♥ cancer! ♥ All I wish for in 2010 is a CURE! ♥ Dear God, I pray for the cure of cancer. Amen. ♥ 93% WON'T Copy and Paste this, will YOU 4 just one hour?!"
So that is kind of funny timing! I'm not a big fan of these messages, so if I have somebody who is making them regularly I will probably remove them from my newsfeed, because what I can't see won't bother me. I do that with anybody who puts up annoying status updates.
