Why does the originator of the idea have to be the only one who can answer the question? If someone has something to say about the idea that they think can improve it, then why shouldn't they answer? If they don't have anything constructive to say then it's simple - don't post anything at all! As for the dartboard idea: I see what you pointed out as a flaw with the idea that may be hard to work around; perhaps we can just keep improving the speed with each successive round? I honestly don't know.
