As for anyone else's projects, even though they promise to put you in front of the right people eventually, you have to have some small-time prototype to show before they put you through to the bigwigs. Whether you use the $15,000 offered to create that prototype or already have one doesn't matter I guess, however what does matter is that for improvements in ERP/CRM/WebOS/somebigtech there aren't any small prototypes that could represent the idea's viability better than a PowerPoint presentation already does.
So how about judging the idea just by its presentation itself? The other problem is that PG/RTM/TB aren't exactly industry veterans themselves. Any Dilbert in the country has a better clue of how things work in, say, the corporate world than a painter and a university prof. They wouldn't recognize a better CRM solution if they sat on it, and neither, I am assuming, have friends in the right places that they could consult on the matter. So seems like inventors would be better off beating down the door to the real guys.
