I have to agree with the others, I don't think I would feel safe in using my credit card on Facebook, for anything.  Not any time in the near future at least.

But since I'm usually drawn to the weird and horrific (like gawking at a traffic accident) I usually spend some time on FB to see which one of my friends' friends' friends are having a bowel movement, and now I can find out the exact location where they are having one too!

BTW, for all my friends on Facebook, sorry, you have already missed my bowel movement for the day.   And this thread/post is taking an extremely ugly turn.....please continue as you were!
