On a recent blog post Seth Godin has a link to Google Spreadsheet. Both Yahoo! and Microsoft have webmail clients that mimic Outlook, a desktop application. The trend toward replacing common applications such as word processing (Writely) and (with Google Spreadsheet) spreadsheets appears to be spreading. This is damn cool. On Google Spreadsheet, you can keep your files on-line and access them from anywhere, and determine what other Google users can access them. Surely some pundits predict that webApps will replace conventional ones, which will significantly decrease the importance of operating systems. (Paul Graham wrote about this five years ago.) We’ll see.
