It's a huge problem that a lot of people are noticing. Everyone from HotWired to my own dear mom have pointed it out in recent weeks. Everybody suffers because of this problem.
Companies suffer, too.
Ironically, these companies are spending money to keep online the very website that tarnishes their image. Design your site to minimize the work involved in updating the content. This includes using the right tools and presenting the right kinds of information. Make a commitment to update your site regularly, and stick with it. The Creative Good mission is to make the Internet easier to use, and by gum, that's what we're gonna do.
