每年一月，比尔·盖茨都会撰写一封年度公开信，评价比尔及梅琳达盖茨基金会的工作成果，以及基金会达成目标的进展情况。在今年的公开信中，比尔·盖茨表示，创新将成为影响未来社会的一个要素。信中也说明了基金会将会为哪些理念提供资金支持，并将谈论到每个项目的益处，时限以及风险。

Every January, Bill writes an Annual Letter, which includes his thoughts on the work of the Bill & Melinda Gates Foundation and progress it is making toward achieving its goals. Interest in the 2009 Annual Letter was one reason Bill decided to create the Gates Notes website.

I recently wrote my 2010 Annual Letter, which will be posted this week. In this year's letter I talk about the importance of innovation for solving some of the world's biggest problems.

Melinda and I see innovation as the factor that will make the difference between having a bleak future and a bright one. The letter explains how we decide which ideas to fund and talk about the benefits, time frame, and risks of each one.

I decided to write an Annual Letter because in 2008, Warren Buffett encouraged me to find a way to share my thinking more broadly about the foundation's goals and to assess as frankly as possible our progress toward achieving these goals.

I wrote my first Annual Letter in 2009, and I have to admit I was surprised by the outpouring of interest after it was published. I never anticipated that so many people would get in touch to ask that I continue to provide updates on the issues I covered in the letter.

My plan is to write a letter at the end of each year to provide my honest assessment of how well the foundation is doing in its work to improve health and reduce poverty in the developing world and improve education in the U.S.

In many ways, the Gates Notes is an extension of the Annual Letter. I will write some about foundation-related topics as well as work that isn't related to the foundation. (The foundation-related posts will appear on gatesfoundation.org as well.)

My goal for the website, as it is in the Annual Letter, is to be as candid as I can about the issues I care about. Hopefully, people will find some ideas and information that will help them think about how to tackle some of these issues, too.
