A Google Calendar event-adder system would be dead handy. An example:
Scale With Rails has three events. New York, California and Frankfurt. All on different days and in different locations. I want to go to the Frankfurt event. To add it to my Google Calendar requires more work than I should have to do, even with the natural-language feature of GCal. Plus I am prone to typos and may enter the wrong date or be in a rush and forget to add the location. What should happen is that next to each event is a link saying “Add to calendar.” I click it and it adds the event with the correct details to my Google Calendar.
What with the Google Calendar API this shouldn’t be hard to implement. A middle-man website could handle it all. There would have to be some authentication of course. Event organisers can setup events on this website and be given an URI that they can put on their website. We could even suck data out of Upcoming and the other event websites that already exist.
All we need is the Event to Calendar link.
