Armory Park Utterology
Something I've been meaning to mention for a while now -- my phonologically-oriented colleague Adam P. Ussishkin has started up a blog, Armory Park Utterologist. Its topics range from the future of his Tucson neighborhood, Armory Park, to the future of phonology. (Hmm -- very futur-y topics, I now notice -- and when you google 'Utterologist', google wonders if you meant 'Futurologist' -- Coincidence? or conspiracy?)
Anyway, in his 'future of phonology' post he reports having constructed a (lexical) neighborhood-density calculator for Hebrew. Very cool!
