Do you mean that if one posts a question here on Agnostic.com which requires a thoughtful answer that, as the original poster, one should also provide their own thoughtful input?

If that is what you mean, yes, I agree with you. Well, let me clarify. Not that they should. More like that I wish they would. At the very least it gets the conversation going.

I think if you want an honest and open answer, and fresh thoughts, it might sometimes be best not to lead the discussion into just an argument about why you may or may not be correct, but wait a bit before weighing in to see if you learn something before sharing your conclusion. If you have a question, it usually means you don't yet know the answer. Just my thoughts on it.

Then again, sometimes it's best to put your thoughts right out there - just depends on the question I guess.

Yes, probably, but sometimes what one person thinks is a thoughtful question another doesn't.
