How To Design A Good API

I found this elucidative presentation on principles of designing a Good API. This is presented at Google Tech Talk by Joshua Bloch. Joshua is a Principal Engineer at Google and was former developer at Sun Microsystems. Some of the things are discussed in his Effective Java book which every Java programmer should read.
In fact I got US edition this book while in india. I wish if indian edition of this book also would also be available. Interestingly this video as recommendated by Google based on my browse history. Google is really cool...
