The question mentioned by the original OP was "My last question (just now) asked about potential maintainability issues involved with a certain approach to CSS layout." which doesn't appear to be very open-ended, at least from my interpretation.

I'll be honest, I mainly knew what the answer to your question would be, but I tried to put myself in the shoes of a newer user trying to understand what questions a person should ask on SO and was curious of maybe things were different.

And the answer appears to still be some form "you won't know until it's closed".
