You know those too-bad-to-be-true mailings that offer to let you turn expiring frequent flyer miles into magazine subscriptions? Turns out that, at least in some cases, they’re even worse than advertised. Google SEO god Matt Cutts had racked up about 15,000 miles on U.S. Airways, and was looking for a way to cash them in before they expired. The magazines seemed like a better deal than just letting the miles turn to vapor, so he went ahead and ordered a bunch, and waited for them to arrive. And waited. And waited.
