    18. 18. 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)

    33. 33. Conclusions • existing Web 2.0 services can be used effectively for extension communications • integration into a traditional website is possible • social media can increase your reach • golf course superintendents need more training in the development and implementation of fungicide programs
