For instance, DeadSocial allows you to schedule messages, images, and videos that can be released any time in the next 999 years. Here's a tip: If you're spending time planning the perfect status for your distant relatives in the next millennium, you are wasting this life.
If you don't have time to plan a thousand years' worth of updates, try LivesOn. This Twitter program will learn your likes and habits while you're alive and then continue tweeting "for you" after you die. What type of nuggets of wisdom can you expect your friends' cyber-ghosts to share from the digital afterlife? The official LivesOn Twitter account retweets the stuff their users have generated through the program, so let's see:

"He died like he lived: trying to fuck pandas."
We swear to whoever the appropriate deity might be that those are completely real (albeit tweeted by pre-dead beta testers, apparently).
But Eterni.me takes this idea the furthest. It also collects and tries to "understand" information about you, but with the end goal that it could one day have actual online conversations with your friends and loved ones, standing in for the dead you. Theoretically, your grandchildren might be able to ask a computer avatar of yourself what kind of stuff you were into, and you just have to hope it didn't keep track of the number of times you watched that My Little Pony furry porn.
