I wish you luck, more competition in the browser space is sorely needed. But please, please spend more time thinking about your finances. The surface of planet "Startups That Will Figure Out A Business Model Later" is like 99.9% graveyard. You're going to be asking people to depend on your software for an extremely important part of their lives. If you don't have a path to sustainability, you're going to do a lot of harm when you close up shop.

Between the lack of a business plan and your responses about licensing, I'm afraid I feel you're coming at this from a naive point of view. This is a seriously important line of software you're entering, please do take some time to take it seriously.

Will watch your progress and again, I genuinely love to see your project. Good luck.
