Idea of company, what you think?
Hey, since a couple of months, I had this idea and I was really excited to finish my last classes to start my company. However, as you will probably guess it, it looks a lot like google calendar..

Here it is: A web/mobile app to add events/tasks and being able to share everything with friends. Here's what differences it from the actual google calendar:
- Possibility to follow friends and have a live feed of what they are attending right now.. (i.e. Marie and Bob has just attended mathematic class, etc.)

- Possibility to see in real time who's present in your event. For instance, suppose you go to a python conference, if someone that you don't know is attending this conference, it will be possible to add this contact (if this person wants, of course).

- Possibility to ask friends for When and Where they want to do something. For instance, I can invite 3 of my friends for tuesday, wednesday and friday in 3 differents restaurant.. in real time, they see the invitation and choose what they like.. and when I know what my friends want, I can create the event.

- I thought of a kind of concept for a smart task where your tasks follow you in your calendar during all day instead of being static or in a list. For instance, when I'll look at my calendar, it will say: Do X homework, and then, I can either do it or skip it by saying to not bother me with it for a week.. and, there could be a kind of smart IA that could predict the more important tasks (My homework for tomorow might be more important than the one in 1month, or whatever..) The important part here is that all tasks will "pop" in the calendar presently (and of course, it will be possible to see them all).

- Smart alarm such as: Always wake me up 1 hours before my first event in the calendar school. This could be useful to me at least.

- Smart reminder such as: Keeping a feed of reminder of events in exponential or something time. For instance, my event of a python conference in 6 months could automatically remind me in 5 month, then 2 weeks before, then the day before.

- When an event is created, it could be possible to add it on facebook in the same time.

- Now this one was for the long term.. but hey: dentist could add events to you without knowing your email address or your account. How? Because you both know your dentist ID. The dentist would add an event to this ID and on your side, you'll add this ID to your account. This could make the decision to switch to this technology really easier for companies. The school could show your schedule with your personnal school number, etc..

- People could search public events and sync the calendar in their own calendar (But now, it's possible in google calendar). So, it would have been possible to register to hockey matches, BUS schedule, artists tourney. And, people could register on a feed of publicity event that they like.. For instance, suppose I'm in the mood of buying a new laptop and I don't know what a mac is, I could register to laptop publicities.. so all publicity shown to me would interest me. I think this could be awesome for seller.. I could register to special 50% days to buy my new tv, etc..

- Finally, for the money part, I thought every user would have it free. However, company could pay to have their own domain. For instance, if my university would like to show me my schedule with my number, they could go public.. or buy their own private domain with like 1000 possibile calendars. My-university/mathematic/mat1141 would be official instead of mathematic/mat1141 where everyone could create public events of that name.

- Also, seller would pay to be able to show publicity.

So, as you see, this is a big project and I really wanted to start it. However, I'm not sure anymore.. does it make really a difference between this and google calendar? Could I use google calendar to develop something like this? Should I find a new idea - something simpler maybe?

Thanks for your time,
