Using other people's blogs as debate forums
I made the error of posting a response to a comment by Brooks, B Rational, on Diane Lim's blog, http://economistmom.com/2010/02/why-paygo-isnt-enough-but-why-well-take-it/#comments , that had nothing to do with her original posting. This lead to an exchange of comments which which got nowhere. The final comment there is Brooks accusing me of copping out. I have learned (or should have learned by now) that Brooks has endless ability to keep adding comments with more questions that take up space without shedding any new light. Eventually I am compelled to give up, so I am always the one who cops out.
1) Is it appropriate to start a debate on someone else's blog that does not pertain to the original post?
2) Does Brooks "win" every debate by being the last one standing?
