Calender++
I think Brian Aker
Every website that has events should publish an ical file. Just like they publish RSS, they should publish their events based on dates. ICS files with VCALENDAR entries are easy to publish.
Should have a look at Upcoming.org , but then we can't expect everyone to fill in their event there. And I also lost track of the events I wanted to publish there but never get around doing so.
But in general, as I mentionned earlier
solving the Calender problem isn't easy.
