Can crowdsourcing improve open data?

I’ve written a guest blog over at the London Datastore about efforts to provide really good open data through OpenStreetMap.

My main example is my work on OpenEcoMaps, which mixes imported (and checked) open data with crowdsourced OpenStreetMap data to provide a great environmental geodata resource. My concluding hope? That “this will spur growing interest amongst data hoarders in data collaboration rather than plain old data dumps.” Have a read.
