"Wow, that's useful advice" rarely translates into practicing said advice. Often we don't have an immediate opportunity to practice, and then we forget. 

Boomerang is an experiment that helps you internalize and remember advice. Send it something worth remembering and it will remind you sometime in the future.

You're free from the need to choose when, or how, or where. Free from the stress of needing to remember to check your notebook sometime later. That's part of the beauty. Taken out of context, the idea just might transform into something better. 

Try it out by sending an email to Maybe just send "Try using Boomerang again."
