Nostradamical lets users, after a quick and easy registration, very easily create a prediction on just about anything and lets people vote on it. It could be another opportunity for English Language Learners to write something for an authentic audience.
Users can easily import images from the web to liven-up their predictions, as well. I only took a quick look around the site, but I didn’t see anything that would be inappropriate for classroom use.
Thanks to TechCrunch for the tip.
