I’ve been told that there’s a commenter on Zero Hedge who is pretending to be me. Not so. I publish my column and this blog; there is a Twitter account, NYTimeskrugman, that is a Times robot that tweets titles of columns and blog posts; and that’s it. I don’t leave comments on other blogs, I don’t have another Twitter account, Facebook account, Google Plus account, or any of that. Hey, I am trying to have a life.

And I do think that it’s kind of curious that I’ve had repeated incidents in which people pretend to be me, usually in an attempt to make trouble. Is my real output so hard to criticize that people looking for a way to discredit me have to make stuff up?
