Clayton Wilcox, superintendent of Pinellas County Schools (Florida), the 22nd largest district in the country,  today announced his resignation. After years of controversy, the district just released zoning maps for its new student assignment plan, which doesn’t take race into account when apportioning pupils to schools. The maps are bound to stir things up, and perhaps Wilcox wants to avoid the forthcoming scuffles.

(For fourteen months, Wilcox actually operated a blog, which he briefly shut down, ostensibly because too many comments on his posts were insulting. Flypaper scoffs at such blogging weakness.)
