Long Live the Marginal Revolution!

It looks like our short-lived technical difficulties are over (cross fingers!). If all continues to be well we should now be available at our permanent address, www.MarginalRevolution.com which is easier to remember than http://MarginalRevolution.blogs.com (the old address will continue to work just fine of course as they map to the same place). I have a question for the techies. Do different browsers use different DNS servers? I was very puzzled to find that the new address worked from IE at least several minutes earlier (and perhaps longer) than from Mozilla. Email me if you know the answer.
