Can Haste Make Waste when time is of the essence?

I love 350.org: www.350.org/vigil-vid
The magic number of 350 is critical.

But the devil is in the details. I worry about adequate oversight in allocations.
I worry about vague language based on differing carbon emissions models.
I worry about adequate transparency.
I worry about small successful programs becoming engulfed in flashier ones with better photo ops but less track record.
I worry about all the ways movements have tripped on ourselves in the past.
