This month, several features have been added to Google Spreadsheets. As you can tell, the one I'm most excited about is the ability to share a Google Spreadsheet with anyone. When you enable a spreadsheet to be viewable by anyone, it creates a special URL that can be sent to anyone; you can invite others to view your spreadsheet from here, as well.
Though it requires the invitee to have a free Google account, this will be a powerful, easy way of sharing important, detailed information to anyone you want. As a matter of fact, it just so happens that I have some important information to share with you in my own Google Spreadsheet that I've created for my readers. OK, maybe it's not that important, but I share it all the same!
Other features that Google has added include the ability to convert to PDF or Open Document Format (ODF), and the ability to print your spreadsheet easily. Check out their What's New page for more information on all of their new features.
