Instead of writing an email or sending a text that will arrive instantaneously, send a postcard that won't arrive until you want it to. Perhaps you want to remind yourself of something in five years time or make a prediction for the world to read in ten years time? Write a postcard, upload an image and select the keywords you want search engines to index. Somewhere on the vast Internet there’s a message waiting for you.

Example

1. Maria is 60 years old and is writing with unborn descendents in mind.
She adds a picture of herself as a young woman.

2. She's doesn't want anyone to read her message before the 22nd century,
so sets a 91 year delay.

3. Feeling that her words would benefit all young people of the future, she
chooses keywords like "wisdom" and "great-great-great-grandmother."

4. Sending the message she can relax in the knowledge that future search
engines will find her letter and point people to it until it is revealed.

5. On new years eve of 2100 someone follows a random link, looking for
advise, and finds Marias letter from the long past.
