What do you think of Twitter's 280 character experiment? Prefer 140?

Twitter shocked the world by announcing an experiment: going away from the iconic 140-character limit and expanding it to 280. Comment below and vote here https://twitter.com/ProductHunt/...
@producthunt What are the metric that they are trying to improve with it ? If they are looking for more time reading, I would prefer to test and improve a tweet storm feature, which is already used by the user. Keep the scarcity of 140 and make a user behavior into a real thing, not a workaround.
