Successful promotion of your product…

Share what you have, why not open source? This way you give the power to the people that already believe in you.

Make your product fashionable, interesting, edgy, so that people will want to talk about it and will feel compelled to become experts in it.

Does the best idea win? No… well sometimes, but who could tell because new ideas are infinite.

If you don't believe in you then no one will.
