This is a solution but it isn't the solution. Email doesn't need to get better it needs replacing. I'll give everyone a hint: Basecamp almost has it right. If you focus on groups with the option to drill down to projects, individual schedules, and to-do's all in one then you're on the right path. On top of that the solution needs to be something everyone is using or can begin using quickly. Think Facebook. It's hard to explain but when you see it, you'll know it. I'm working on it myself.

Not that this isn't good. It really is but I can see it being unnatural for some. If only there was a way to do this without changing so much of your usual habits and kind of fitting yourself into a workflow someone else designed then it'd be massively popular. That said, this far from unimpressive. It's awesome and I'm sure a ton of people will find it super useful. But even the people who are getting Nigerian inheritances need some love. If someone built something that addressed the people that would use this but is also useful to the inheritance people I bet you anything those non-power users would actually find ways to use it even if they aren't busy a lot like how people who aren't social butterflies still log into Facebook and post status updates once a day.
