I like that you're able to type anything in the text field, so your message can be as specific, cryptic, or silly as you want. And, according to the site's FAQ page, any data is erased after it's sent to you as a reminder, so you don't have to worry that your reminders are being stored somewhere. You can set reminders far into the future, too. Right now the calendar reaches 2011. I've already programmed reminders for all of my friends' birthdays and the day my credit card bill is due — no more excuses for forgetfulness!
