Hello World

Hello World is a science fiction short story speculating on the possibility that an extraterrestrial intelligence could observe humanity via social media. Professor Franco Corelli has noticed something unusual. The twitter account @QuestionsLots is harvesting hundreds of millions of tweets each day, but never posting anything. Outwardly, this account only follows one other twitter account—@RealScientists, but in reality it is trawling every post ever made by anyone on this planet. Could it be that @QuestionsLots is not from Earth?
