OpenIDEO
OpenIDEO is a global community that will draw on your optimism, inspiration, ideas and opinions to solve problems together for the collective social good.
OpenIDEO is a place where people design better, together for social good. It's an online platform for creative thinkers: the veteran designer and the new guy who just signed on, the critic and the MBA, the active participant and the curious lurker. Together, this makes up the creative guts of OpenIDEO.
