Time to invest a little effort to understand and appreciate the pioneers. Doug Engelbart is someone I followed from my earliest tech days and he is even a bigger personal hero of my wife who spent time with him at an Apple Distinguished Educator training back in the day (she was in the 3rd class of ADEs).
Engelbart did the mouse and conceptualized windows. My interest was in his concept of augmented text. Some of these ideas have influenced my thinking regarding text annotation as a way to advance reading.
