Over at Belmont Club, Wretchard reveals all!
This model is only partially functional now. People who knew me in the past, as well as my colleagues at Pajamas Media, know perfectly well "who" I am, although I think that information is totally irrelevant. Since the model of anonymity is failing, I'll disclose the boring details.
Whether or not Wretchard blogs anonymously, Belmont Club is still one of the finest analytical sites out there in the blogosphere. Cheers, mate!
