This is morbid, but fascinating. We've become accustomed to chronicling our lives on social media sites and now a site is helping do the same in death.

The Tweet Hereafter is a catalog of the final tweets of newsworthy, famous and infamous folks who have passed away.

The site is the brainstorm of a couple of technology professors who collected the tweets for years, but only recently started publicizing the website following the death of Reeva Steenkamp, the model shot by "Blade runner" track star Oscar Pistorius.

Each final tweet is followed by the person's date of death and a link to their Wikipedia bio.

It's a somber and disturbingly seductive read and a reminder of our digital mortality. If nothing else it may prompt you to vow to treat every tweet like it's your last.
