Activity suggesting software

one liner: make a software that would recommend activities to do (for work or entertainment)
-or the integration of scheduling software with product searches.

Before I go into the details, this idea came up when I was thinking about how else to do advertising in the future. Advertising is THE way of making money online, all other options aren't really turning out to be great business plans. In general, I do not agree with the assumption that money making businesses are inherently unconscienable. In a perfect world, money would represent the value that a business offers, and advertising offers a lot of value to the world. Annoying advertisement and false advertising do not add value in the big picture of things.

During the course of the week, there are times where I find myself wondering what to do. I have lists of TODO for home, and for work, but I don't really have a habit of going to those when I have free time. It would be nice if a schedule / daily planner would be able to suggest things to do next. For work, it would grab your todo list, and your boss's todo list, and you coworkers todo list, and combine them in a way that would maximize productivity. For entertainment, when it sees that I have some time off, it could look at my history and suggest activities for me to do. If I want to do something with my friends, it could look at their iteneraries and offer suggestions as well. Here is where the revenue would come in for this idea. Depending on who I was with, what time of day it is, or a bunch of other factors, it would be able to tell me that there is a sale at so and so place, or new movies that came out that I want to watch, or that there is a new game that came out. Companies would be able to have targeted advertisement for people that want to do certain things.

I can plan to hang out with a few friends, and the software could be able to suggest restaurants to go to, or things to do. On the advertising side, companies could develop activities for people to do, and advertise it to the people who are interested.

Since we are often defined by the things we do, I hope that such a software would help us to become who we want to be.
