"Have you ever wanted to maintain a bunch of information about meetings, events, or conferences in a Google Spreadsheet and have that information be easily shared and searched? Well, at Google, we do just that with our Developers Event Calendar on code.google.com. The data that feeds into the calendar comes from a large variety of Googlers across the entire company — many of whom have edit access to a Google Spreadsheet where the data is stored. In the spreadsheet, unconfirmed events exist along with well-publicized engagements. People even sometimes enter prospective events — even before a proposal is submitted or a potential sponsorship investigated. An 'editor' is responsible for publishing events and recording the published events on a column in the spreadsheet."
