Fog Creek renamed to Glitch as we transitioned from being a bootstrapped product-incubation lifestyle company to a single-product VC-backed startup. I think of the Fog Creek storybook closing with that rename, since Glitch always had a very different business focus, but technically (and perhaps culturally) they're of the same lineage.
In other Joel track record exploits, he's also our co-founder over at HASH.ai [1] and a driving force behind the Block Protocol [2][3]
hash.ai and the "block protocol" sound like crypto shams. Nice to see something different, although I feel like the branding really, really makes it seem like crypto.
