The document discusses different types of people in adopting new technologies using the metaphor of a pencil. It describes the "lead-ers" as the early adopters who enthusiastically share their experiences. The "sharp ones" learn from the early adopters and implement technologies effectively. The "wood" would use technologies if given support and training. The "dead wood" cannot be convinced to adopt new technologies no matter the efforts. The "eraser" undoes the work of the early adopters by criticizing new approaches. An optional "hanger-on" attends seminars but does not implement anything.
