future-you, I like this. I recently stumbled upon futureme.org It's a service you can use to send yourself an email in, say, 5 years. Around christmas, I wrote myself an email* to read in 10 years. There's something quite intriguing about making a bunch of predictions.
[*]: That email actually only contains a sentence: "Hey, here's something you need to read today. Search your journal for $RANDOM_UNIQUE_STRING and you'll find an entry written 10 years ago for you by your former self."
Do you put in any effort to make it readable for others? I imagine this is a significant part of blogging.
