How fun would it be to freak out your relatives from beyond the grave? Good fun! 

LivesOn will takes over your Twitter account after you die by sending out new Tweets based on your current likes and tastes. 

All you need is an executor to decide if our account stays alive long after you're gone. From their website: "When your heart stops beating, you'll keep tweeting." Look for it to live next month. 

This would totally be worth if my daughter started dating someone, and I could tweet "he's worthless" from beyond the grave!   Muh-hahhahaha....
