How did you get sarcasm from that post? Kalvin clearly seemed to enjoy the idea, particularly because he/she is currently in a relationship. I am in a long-distance relationship currently and I think "thumb-kissing" and the whole app in general is really brilliant. I'd use it, but unfortunately she's got a Blackberry.

I'm curious: are you in a relationship? That's not meant to be a jab; I just think that there's a pretty big gap in "getting" this idea between those in relationships and those who aren't.
