People who cruise the web for fun and recreation aren't the ones I'm concerned with. They'll get their chuckles someplace, although probably not on a .mil site. Using graphics that take several minutes to load. Including links to places that have no earthly relationship with the mission of the presenter. Presenting zipped files or files that must be downloaded and opened under a particular software application.
Users expect the web to appease their instant gratification syndrome.
After all, who wants to tap into a web site looking for a point of contact and a phone number or e-mail address and be forced to download the entire phone book, unzip it and open it under whatever word processor you don't have. I don't know about the rest of you, but for me if a web site requires me to do anything more than digest the information, I scratch them off my list. For you web publishers who might be guilty, take a look at how many hits you're getting. That tells the story more clearly than I ever could.
