Auckland based site, Eventfinder, have been rolling out heaps of new features recently with a focus on the social networking aspects of finding and attending events. Each registered user gets a profile page and can add friends to their network to keep up to date with what events their friends are attending.
This is a great use of social networking and they make it very easy to keep track of the events you and your friends are attending.
There are lots more features planned too, such as RSS feeds for your favourite events and the ability to publish the events you are attending directly to online calendars such as Google Calendar, as well as other social networking sites like Facebook and MySpace. You can view my profile through the link below and if you add me as a friend you’ll be able to keep up to date with the events I’m attending.
