I am not EJ and don't know him personally beyond reading his writing here. I think the softness in gold isn't why he has wrote less recently, but rather that he has been more busy working on startups like VirZoom. Gold may remain weak in Dollar terms until oil prices begin to shoot up. And that could perhaps be a year or more out from now.

I'd guess that when the macro-economy starts melting down more EJ would start writing more. But he also mentioned his willingness to work on & invest in startups was predicated on the thesis things wouldn't come crashing down soon.
