Events:

Have an event coming up? List it on these sites:

6.) Upcoming -Upcoming is an event sharing site hosted by Yahoo. Key sharing points: share your events with your friends

7.) Facebook - Yes, I'm listing Facebook again. But Facebook events are another great (and frequently used) application for sharing events. Key sharing points: news feed update (when creating, attending, commenting on events)

8.) LinkedIn - Similar to Facebook, LinkedIn has an event posting/sharing feature. Key sharing features: posted in LinkedIn network updates (when creating or attending events)
