First came the primordial soup. Thousands of relatively simple single-celled web sites appeared on the scene, and each one was quickly claimed by a multi-functional organism called a "webmaster." A symbiotic relationship quickly became apparent. Webmaster fed web site. Web site got bigger and more important. So did the role of the webmaster. Life was good. Then, bad things started to happen. The size and complexity and importance of the web sites began to spiral out of control. Mutations started cropping up. Strange new organisms with names like interaction designer, usability engineer, customer experience analyst, and information architect began competing with the webmaster and each other for responsibilities and rewards. Equilibrium had been punctuated and we entered the current era of rapid speciation and specialization.
