Don't they both count as XP? If not, I'm never going to laugh again, I've got a guilty feeling I've got no xp. Okay, that's bad. I should never attempt to sing.
Now, it does raise the question...how do y'all decide when to click the buton.
"Laugh with this post" is easy. Did I laugh. I click on it. Unless you make me laugh so hard that I loose fine-motor control in my fingers and end up clicking the close-tab "x" on my browser instead.
"Give XP for this post" = OW. Your post makes my head hurt. Must be good.
