Lambda the Ultimate is an outstanding programming languages weblog that I read frequently. Lately, though, the signal-to-noise ratio has been dropping, and I've felt the need for a way to eliminate some of the chaff. So, I created Lambda the Ultimate Killfile, which is a Greasemonkey script that prunes out entries from people whose comments you'd rather not read. Simply install, then use Greasemonkey's "Manage User Scripts" dialog to edit the script. Add the names of the users you don't want to see to the "users" array, and you're off and running.
