Bob Bickel is one of the nicest persons I know. He's also quietly had a huge impact on the software industry, first pioneering the web application server market and later turning the JBoss project into a successful business (and flipped to Red Hat), pioneering the current trend in "professional open source." I thoroughly enjoyed working for him back at Bluestone and HP. Despite a mild demeanor, he drove his team extremely aggressively. I'm not sure I showed proper respect for what I learned from him at the time, but it shaped who I am today.
Cool to find he has a new blog. Looking forward to reading it on a regular basis.
