...50% is a lot for coming up with the idea...
Think of it as 20% profit to the developer (though, if you truly expect success, a flat sum paid for the work involved gives the programmer more confidence)
wouldn't you have liked 35% of microsoft (hey! no one knew what will happen) instead of 50.000 $ back in the 80's?
And I am sorry, but I personally would not invest any amount of work in a business where I will get a flat pay when that business can profit after my work forever. Besides think how bad it is for me: I pay a guy 100 coins (as example), he does the work and then he leaves....he has no interest in staying to further improve and work on the idea. 100 coins later, he takes off and I am where I started. I need a partner not an employee.
...the rest into operating costs. Server, bandwidth, advertisements, support, oh shit fund, etc. If you end up with a large operating fund, you can either expand or have bonuses (to yourself or anyone operating with you).
Operating costs are minimal. Although I appreciate the feedback and arguments, an internet based business has some pretty low maintenance costs.
Besides, I do not see the point of you making up some percentages to suit your individual preferences when you have no idea about what the business is all about.
I do some web programming, but I've got absolutely no idea whether I want to be involved in this. And there is no way in hell I'll sign an NDA.
Please tell me why you left this reply in the first place then? I fail to see the point.
Ideas are a dime a dozen.
Thank you for sharing your oppinion.
