There’s no limit to the number of good ideas out there that could help change the world. Many times, innovative solutions grow from previously existing ideas that are tweaked and customized for current needs. That said, below is a list of Idea Hubs from around the web to stimulate your mind, from conferences to user-submitted idea warehouses to resource centers. I’ve also included the twitter handles of those that have it. Enjoy!
