I do something similar, but offline. I have a nice notebook and I write letters to my daughters. Generally mundane day to day stuff or events that happen. I hope to give it to them when they are older. I do like the idea of an email though where you can send stuff for the future. I try to print out physical photo books for them to look back on, but I'm not very disciplined on that.
