The latest twist on technology - sending emails to your future self:
The site is one of a handful that let people send e-mails to themselves and others years in the future. They are technology's answer to time capsules, trading on people's sense of curiosity, accountability and nostalgia.
"Messages into the future is something that people have always sought to do," said Paul Saffo, director of the Institute for the Future. "In a way, it's a statement of optimism."
Matt Sly, 29, came up with the concept for FutureMe about four years ago. He was inspired one day after recalling how during his education he had been given assignments to write letters to himself.
Sly, who partnered with 31-year-old Jay Patrikios of San Francisco on the project, said the site has made maybe $58 through donations. He is adamant that FutureMe is not a reminder service and that users should think long-term.
The site lets people send messages 30 years from now, though Sly's numbers show most users schedule their e-mails to be sent within three years.
"We want people to think about their future and what their goals and dreams and hopes and fears are," he said. "We're trying to facilitate some serious existential pondering."
He said a large number of the messages sent do one of two basic things: tell the future person what the past person was doing at the time, and ask the future person if he or she had met the aspirations of the past person.
"The tone of the past person is not always friendly," said Sly, now a Yale University graduate student. "It's often like 'Get off your lazy butt.'"
Of course, some things are probably best left relegated to the past.
"The lesson about all these things, it's the lesson from time capsules, is you have to be careful lest you set yourself up for enormous embarrassment in two decades," Saffo said. "Do you really want to be reminded that you thought ABBA was cool?"
