If I ever climb to the top Mt. Everest, I will tweet, like this guy. From Gizmodo:
English mountaineer Kenton Cool (no, really, that’s his name) made the world’s first tweetand video call from the top of Mount Everest yesterday. He used a Samsung Galaxy S II to tweet at SamsungUK, which is using this event to do some pretty smart marketing. It was Cool’s ninth time summiting the mountain—kind of impressive considering Everest claims a life for every ten successful summits.
