jQuery.Rule (via) jQuery plugin for manipulating stylesheet rules. For me, this is the single most important piece of functionality currently missing from the core jQuery API.

Twitter Don’t Click Exploit. Someone ran a successful ClickJacking exploit against Twitter users, using a transparent iframe holding the Twitter homepage with a status message fed in by a query string parameter.
