Big brouhaha this morning over the fact that Google’s Toolbar “hijacks” 404 error pages and displays their own promo instead. “Google is evil” – say some webmasters.

I don’t see it a big deal. 404 pages are not exactly masterfully designed pages anyway, in fact I’m not really supposed to see them at all.

By the way, it’s not such a new idea either: it’s the very foundation of OpenDNS‘s business model.

Update: Google’s Matt Cutts explains how 404 works.
