In the message about the new badge it said you will soon be able to give it to others.
That would be cool. I was wondering about whether I can gift someone PHUD - which I have since found out means "pussy" in Hindi :D
For the individual account badges it makes no sense, but perhaps there could be some badges that are awarded by a third party. For example, if there was a badge that could be given by a select few who qualify on some metric, would people want it?
