Zapd is a really neat iOS app that lets you create a web site directly from your iPhone or iPod touch. While their claim that you can do it in 60 seconds probably is a little bit of an exaggeration, it's definitely a remarkably fast process and you'll be able to put up a web site in a few minutes. For example, I created this web site using content I created with my phone and content already on it. It's neat because you have plenty of themes to choose from and you can edit the entire site directly from your phone, but the types of content you can add is similar to what you'd find with something like Tumblr. It would be really nice if it was capable of some serious editing. Maybe that's a version that would work better on the iPad. Nonetheless, Zapd is a good app for getting a personal site up quickly in just a few minutes for a grand total of $0.
Zapd is available right now, for iPhone and iPod touch (as well as iPad in non-native mode), in the iTunes App Store. It is a completely free app.
