Hmm... I had forgotten about this, and haven't been on BoingBoing very often since the redesign, so I didn't realize that my userscript from a while back had stopped working. And unfortunately, userscripts.org is dead, so I can't update it there.
Here's an updated Remove Real Stuff script for the redesigned front page (see here for the original):
// @name Remove Real Stuff posts
// @match http://*boingboing.net/*
// @version 0.2
// @copyright none
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js
