+1 vote. I like the idea of being able to show our appreciation via gifts in game.
Personal view: But the downside of it would be the way people keep coming for tips and loans. The intent of this feature would be lost because of them. Their are ways in which such a good feature could be misused . People could demand currency for sending the tag as well. But as is the case with any feature, their will always be some who misuse it and we would just have to put some control to prevent it.
