More restrictions on what someone can put on my todo list. And when someone can put something on my todo list, I want them to tell me more about what they want from me. Do they want me to do something beyond just reading some text? How important is it? (There obviously has to be some mechanism to prevent people from saying everything is important.) When does it have to be done?
Here’s what I want: A price per email. A service that charges people for each email they send me (e.g., $1/email). I get most of the price, the company providing the service gets a small percentage (1%?). With two additional features: 1. The initial charge is just for me to look at it. Then, after I read the email, there is a mechanism that allows me to easily charge more to do what they ask, such as give them Shangri-La Diet advice. 2. I can easily put people on a list that allows them to send me email for free.
Since Google already has Google Checkout, it might be relatively easy for them to add this to gmail.
