Bret Taylor suggests that we need a Wikipedia for data. A lot of potential innovation is being held up because it’s so hard to get access to factual data (esp decent quality data). Statistics, listings, and so on. Taylor suggests a Wikipedia-like repository of factual data freely available to everyone. It could really grow if it caught on – the sort of thing that fosters a sharing spirit. You know that if you add/update/correct stuff (and everyone else does likewise), everyone benefits.
