And you know what? It should act as a warning to anybody thinking seriously about building large-scale semantic systems like the semantic web.
Cyc is pretty much useless (or at least the utility it provides is not exactly setting the world on fire). Until somebody can figure out how to employ an already very mature semantic graph like Cyc and do something(s) truly useful with it, don't waste anybody's time advocating the semantic web.
More imporantly, Cyc is a highly controlled semantic graph, with all of its information carefully curated. Imagine how terrible the results of semantic inference engines will be in the wild-west of the web!
