Benefits of Twitter

Could it be that people twittering are searching for ideas to share? What kind of ramifications on our society will this stimulate for the next 10 years. Will we have found a way to get off the ground and travel to earthly destinations? Will we use only oxygen to do it? When will we translate oxygen to energy we can use to move our bodies? An earthcraft, small enough to house 3 people with a 270kg capacity limit would be a good starter.
