All kidding aside, IE's content rating infrastructure wasn't all that bad:<p>1. It implemented an open standard;<p>2. It actually had a decent UI.<p>Now, you can argue that PICS and such were bad for the Open Web (and you're probably right), but I can't help but wonder if working client-side web filters from the get-go wouldn't have been better than the current state of affairs, which mostly involves technically incompetent legislation that forces infrastructure providers into all kinds of workarounds...
