Someone recently wrote that "the best way to predict the future is to wait for it to happen". Mark Oehlert writes about another approach, the use of "prediction markets". He reviews Web of Fate, a visual semantic analysis engine, and Superstruct, a massively multiplayer online game (MMOG) that tries to chronicle the year 2019. An "idea futures" approach might be interesting for buyers of learning technologies. Which ones do you think are going to last, and which ones will not be around in 5 years? -GW
