Apparently, I'm not the only one who thinks that Google Docs might be very useful for managing wedding planning tasks. The Official Google Blog notes all the ways in which they're trying to help you plan for that very special day.
However, Google's entry into the wedding planning business is uncharacteristically, almost comically, inept. These tools are free. This is not how wedding planning services work. The way they work is, they charge you $50 for things that are normally free, escalating rapidly if there is actual work or materials involved.
