I came across a great website that has aggregated over 150 different noble-cause organizations from around the world for an online competition to win a grant of USD 15,000.
The site depends on the online community to pick its finalists in each category - the categories range from Education to Peace to Sustainable Living and much more.
You can register for free using your email address or facebook or gmail login, and are able to cast 3 votes in each category. The voting closes today or tomorrow so hurry up!
Some examples of projects that are in the fray:
World Social Forum 2.0
Teach For India
…and many more projects in some or the other sector with a noble initiative.
Best thing is - so many projects have come together in one place so it’s much easier for wannabe do-gooders like me (and you too!) to find them, and it's amazing what people can do through collaboration and creativity!
