Time: 15:54. A v.satisfying Google-less solve; my better tushnet led me by a little and I made my coveted "< 2 x Rex" goal.
CrossWorld buzz: Very nice. High-value tiles popping out all over; nice mini-themes w/WHAT-HATH, RUBBERY-LATEX, ALMA MATER-UCLA; some sorta painful fill as Rex notes, but hey. We CrossWorlders can suss out the scrabbliness of a puzz like Justin L.'s and use it to our benefit, as I did in getting EXPLETIVE in the SE, the last corner that fell for me. That's a v. satisfying feeling--nice to be in the club!
CrossOver buzz. Very nice. The poppy, mod general feel here is v.good. I think that general vibe matters more to regular folks than to denizens w/ our more particularized preferences.
