I heard it through the Microsoft Vine.
Personally, I'm not a big fan of Facebook "statuses" and Twitter.... but that's not to say I don't think they can provide valuable and real-time information.... I just don't need to know that you "had a burrito and it tasted good!" That being said, there are some times when I would like to informed as to where my loved one is and that they are ok.
