Send an email from the future

The technology is here, HT Seamus:

TimeMachiner is a new mini-app that lets you email people in the future. Use it to remind yourself to do something that you’ll more than likely forget, keep your future self on the straight and narrow, even wish your friends happy birthday…

Useful for reminding yourself of last year’s resolutions, but beyond that, what economically-interesting applications can y’all suggest?

Update: A loyal reader comments:

I can suggest one interesting experiment. Put up a website which provides this as a service. On the front page, put an easy-to-use form. Make the service free and open. Then have no privacy policy at all, so you can do what you like with all the email addresses you harvest. Then all the helpful bloggers will do your marketing for you. (Step 3: Profit!)

Good point…
