Cute idea, but I think it's trying too hard. You see, they've combined my favourite emoticon, the googly-eyed shocked beyond belief expression, "o_O" with the tired old smiley, ":)"
The problem being that it is untypable. Nobody would ever use that emoticon, because it simply isn't one. It may be ownable, being unique, but I take issue with concepts that need an equation to understand.
