If you’re the type of event planner who’s into spontaneous and open events, your life just got a little bit more interesting. Facebook has just added new features to the “publisher” that let you create and share events in one step. The idea behind the new feature is that, until now, Facebook users who wanted to quickly organize open events either did so via status updates or creating Facebook Events, which you could then share; but now, they can combine both options in one step by creating an event directly through the Publisher.

The Publisher, which sits at the top of the homepage and your Wall tab, now gives you the choice of attaching an Event. Once you select Event from the menu of attachments, you can fill out the following fields:

Once you click Share, the story will appear on your Wall and the News Feed. There is a subtle difference in the story that gets published:

With this new method, anyone can “Invite guests,” so make sure this is the intention of your event.

Sharing events without the Publisher: No “Invite guests” link: less conducive to viral and open sharing.

When you click on the “Invite guests” link, a dialogue box appears, and you can select friends you want to send targeted alerts to. (You can then further edit the event – adding photos, changing settings, etc. – directly within the Events application.)

The addition of publishing Events to the News Feed via the Publisher is another move toward making the Publisher a more powerful tool for creating rich content that friends will find useful, enhancing the overall relevance of the News Feed. And because sharing events through the Publisher is designed to be open to all guests, it’s another indication of where Facebook is headed with a more publicly open stream.
