I began working with the web very early by most standards - in 1993. The college I was attending got a connection to the internet, and shortly afterwards I was experimenting with the NCSA Mosaic browser. When Netscape released a browser update with the new "LiveScript" (what they called it at the time) I was immediately interested and invested a lot of time learning how to use it to enhance web pages. At that time the functionality was very limited and "DHTML" was nowhere to be seen, but it captured my interest because it was something new and different. There were no experts on the language or its use, nor any books or standards. People were just beginning to figure out what it was capable of.
Of course, part of the reason I develop these libraries is also because they meet my own needs. As I develop projects or see needs in the work I do, I have an entire set of tools ready to be used that I fully understand. Since I share the code for free and it gets used by literally thousands of web sites, this also acts as my external testing. My code improves because many people use it, test it, and offer suggestions. Everyone wins.
I currently work as a consultant for a national consulting company. I live in Illinois with my wife, daughter Emily, son Kevin, two dogs, and three cats. I try not to work too hard ;)
