It's really lacking in detail. For instance, are those Dogfish Head IPAs the 60 Minute or 90 Minute kind? Or even 120 Minute? That's the problem with all these "new Lisp" whippersnappers. They spend five years doing Lisp and think they have it all figured out. Once cruel experience forces them to chase down all the seemingly trivial details, like which Dogfish Head IPA they're really talking about, they'll have come full circle back to Common Lisp and be begging shamefacedly for forgiveness on comp.lang.lisp.
