Try Upcoming.org

Upcoming and other event calendars like Eventful not only help publish, gain feedback and build momentum for events, but also invent whole new ways to build and use social capital. They help connect people with uncommon tastes, within and to nearby metropolises. They can even stimulate and feed back demand to launch new events.

By exporting their calendars not only in feed syndication formats, but also as data for graphical calendars, they lead in providing rich semantic Web services. Online event calendars have become very useful.

While there are good feeds and good sites out there for event listings, this is kind of a meta-event listing site – and they’ve got community.upcoming.org, a wiki between developers and users which helps improve upon the site. It’s a great and incredibly useful service.

Definitely worth trying out – here’s hoping it stays as cool when it moves to Yahoo…
