[Kathy Sierra] And these folks have a chance to make a Difference (capital "D") on a scale that most of us will never touch. When Ward Cunningham (inventor of the Wiki, key player in extreme programming, etc.) went to work for Microsoft, much of the software engineering world was horrified that he’d even consider it. But he kept insisting that where better to produce positive change than going straight into the heart of one of the biggest sources of trouble for both users and developers in the software ecosystem?

Kathy really says it all in her latest post - what’s been driving me (and my co-workers) lately. We can make a difference - you have to just tell yourself "I am the pebble that can start an avalanche".
