I use Gmail. I set up a second account which forwards to the first and gets sorted into it's own inbox using Gmail's multi-inbox feature. This way, I simply email myself anytime I want to remember something for later. there are a number of reasons this works well: -Email is a common interface and I'll see it daily so stuff stays in the front of my mind. -Can be added to/updated from any number of devices including my phone, ipod, computer -Searchable and chronological. -Updated/new information can be added by replying to the original thread.
