IEBlog Explains PNG Implementation in IE7

IEBlog : IE7 Transparent PNG Implementation
My name is Sam Fortiner and I’m a developer on the Internet Explorer team here at Microsoft. I joined the company about a year ago when I was given the opportunity to work on IE. Since then I’ve worked on several aspects of IE and recently settled down into the layout and display team. As part of my work in this team, I implemented support for per-pixel alpha in PNGs.

Aside from the fact this is avery good explanantion of what it took to get transparent PNG support into IE7, this post alos illustrates evrything that is good about corporate blogging. Indeed the entire IEBlog is a testament to how blogging can be used to connect with customers. We could all learn from this.
