For me, as a non native with the English language, I associate the action to "pin" something as marking it important somehow. In a way similar to "liking" something but without the emotional aspect of it - leveraging the objective importance more than my personal preference. (And I hope all the years of learning English at school have not been a complete waste. ^_^)
If that is the intention, then I can say I like ("pin") the idea of having something of our own for the (probably) most used action you can apply to a post in a social network.
