I note that Brad Setser has announced that he will no longer be blogging. This is not due to disillusionment with blogging, but his taking a job with the National Economic Council. Nevertheless, this is a loss as he has had the best coverage of a variety of international financial issues, especially regarding reserve balances and China, since he started initially five years ago while still working with Nouriel Roubini. He will be missed.
Another that I suspect may be a disillusionment has been the lack of any postings since June 18 at the high quality http://rodrik.typepad.com, where he has at times in the past questioned whether blogging is a good use of time for a top flight academic economist. Perhaps he has decided not for himself, although without getting around to telling all of us, or maybe he is just on vacation or very busy.
