San Francisco's Crushpad allows anyone to blend, mix, sell, and market their own recipe of vino — and Twitter is doing just that, but it's all for a good cause.
The Fledgling Initiative (@fledgling) "aims to make awesome wine for the benefit of Room to Read, an organization extending literacy and educational opportunities to children worldwide."
Each case sold will provide the funding of 60 local-language books to be distributed to under-privileged kids in third-world countries. A single bottle is only $20, and a case runs at $240; buy some.
This is a very cool initiative, and I think Twitter is taking advantage of the social web in a good way.
