Interesting idea, I sent my girlfriend a soppy message for the heck of it and I'm thinking of sending myself some tech message reminders for example re-check this framework/site/idea/open source project in 6 months.

I'm always finding stuff that I'm interested in but don't necessarily have a use for now or I'm interested in seeing how the project turns out in the future, this will send me a reminder that I will actually take note of.
