Definitely. The more people who get used to using applications that are online-only and who get used to having their data on other people's servers rather than on their hard drive or a USB stick, the more demand there will be for everyone else providing web applications. Plus the demand for broadband and hardware goes up every time something new and useful appears, as some group of people buys or upgrades so they can use the new service (e.g. buying netbooks so more of the family can use facebook at once without buying full PCs; or upgrading to better broadband for youtube). The growing availability of APIs enabling functionality without reinventing the wheel is very important as well.
