Brainstorm with a group of people I respect. Put the idea to the test to foresee inconvenients and opportunities I may not have considered after a long time thinking about it myself.

Then I just go and code the core of it ugly and fast into simple tests to make sure it'll fly.

Then I go out and start building a first release with minimum functionality, release it to a closed alpha test group, iterate, iterate, iterate, go beta and cross my fingers.
