The problem is, I expect reminders to be absolutely reliable. In some cases they could be a matter of getting fired or not, or even life and death, like my weekly "check the lint trap" filter. I'm online a lot, but not 100% of the time. It might work for some things, but I'm not a fan of using different tools for different important things when one general tool will do, there's more to go wrong that way.
