Dien Rice (from an interview):

... What I had in mind was something like the
Buffett Foundation (set up by Warren
Buffett). That is, a charity which invests
some of its wealth in stocks.... The profits
are then distributed to help people or
benefit humanity in some way.

What I like about this is that it could in
principle continue to distribute aid after
you pass away.... I like the idea of
continuing to help people after you have
gone....

First, I started to read up ALL I could on the topic.
That means a LOT.
It took a long time too (you know how big that topic is)...

After a certain amount of time, I started to feel like I was quite knowledgeable on the topic...

Here is what I liked about Buffet Foundation:

No matter how much Warren E. Buffett has been criticized for not giving away more of his billions, he is unlikely to waver from his belief that the best thing he can do is leave all his money to charity after he's dead.
That way, he reasons, he can keep using his investment MAGIC to keep multiplying the amount available for his philanthropy.

Mr. Buffett owns more than 40 per cent of the stock in his Berkshire Hathaway investment company. He has made clear that he and his wife, Susan T. Buffett, will give the Buffett Foundation all of their stock upon their deaths. Such a gift would instantly make the Buffett Foundation the nation's largest, overshadowing the Ford Foundation and all others.

Although Mr. and Mrs. Buffett have devoted many of their gifts to date to the cause of population control, he said that they would place no restrictions on how the Buffett Foundation could spend the huge bequest.
Mr. Buffett: "You don't know what the major problems of the world will be or what the funding sources will be or anything. So they have total discretion."

The private fund, does NOT accept grant applications.

Roger Lowenstein, in his book, Buffett: The Making of an American Capitalist, wrote that Mr. Buffett and his wife were firm believers in population control but for different reasons.

The Buffett Foundation has supported many charities that have no interest in population matters.

Warren Buffett has found an unusual way to fill up the coffers of his foundation.
Mr. Buffett, in his role as chairman of Berkshire Hathaway, has given its shareholders the power to choose the recipients of the company's annual charitable contributions. Owners of stock are allowed to designate one to three charities or private foundations that will receive an amount for each share of Berkshire Hathaway stock that they own. The company then makes donations to the designated organizations by handing over cash or stock.

Each year Mr. Buffett makes his own private foundation the recipient of much if not all of his own shareholder-designated gifts, which allows him to put millions of dollars into the organization that do not come directly from his personal accounts.

Mr. Buffett created a second, much smaller, private foundation in 1990 in order to allow members of his extended family to make gifts of their own.
Each year, this fund -- the Sherwood Foundation, named for the forest in the Robin Hood legend -- allows each of the following to distribute up to $100,000 to the charities of their choice: Mr. Buffett's daughter, Susie; his sons, Howard and Peter; his sister, Doris Bryant; and Astrid Menks, a long-time friend.

Mr. Buffett is quiet about most of his own charitable gifts.
