Socializr is a free web service for sharing event and party information with your friends and they share a fondness for simplicity with Twitter. So it only makes sense they Socializr and Twitter have integrated!
You can now click on the ‘Update Twitter’ link from an event to update your Twitter status with the event name, date, and URL.
Also, you can add your Twitter URL to your Socializr profile, and your Twitter updates will automatically be integrated into your Socializr user page.”
