IT's not just Google that allows you to put spreadsheets on line. Here's a worthy competitor: EditGrid not only offers all the standard spreadsheet tools but it also adds features such as live data feeds right into your spread sheet. Sharing is a big part of EditGrid, and they emphasize that you are always looking at the most recent version, no matter who edited it. The service is free for individuals and costs $5/month for a business. It is definately worth a look.
