and that’s what was on the schedule.”
18. Every golf course is different.
Climate, microclimate,
expectations, and
management styles vary.
19. How do you decide when to make changes to your program?

22. What is Web 2.0?
“The Web we know now, which loads into a browser window in essentially
static screenfulls, is only an embryo of the Web to come. The first
glimmerings of Web 2.0 are beginning to appear, and we are just starting to
see how that embryo might develop. The Web will be understood not as
screenfulls of text and graphics but as a transport mechanism, the ether
through which interactivity happens. It will appear on your computer screen,
on your TV set, your car dashboard, your cell phone, hand-held game
machines, maybe even your microwave oven.”
--Darci DiNucci in Fragmented Future (1999)
