Perhaps replies should include the business(es) that was/were yielded from the the steps outlined.
I'm all for discussing ideas, but this question is more about getting better results than merely throwing out "this is how I do it".
I'd want to know how the dropbox, reddit, google, basecamp, balsamiq, uservoice, pbwiki, weebly... idea-flow worked.
Not so much the "yeah this is how i come up with ideas that never really ...uhhh...worked out ....".
No offense of course, but just so we can be clear on the matter!
