I was going to write about the Google Toolbar, and why I like it as I liked Third Voice way back when, but Cory beat me to it on BoingBoing:

It's not a service I'd use, but I believe that it's the kind of service that is vital to the Web's health. The ability of end-users to avail themselves of tools that decomopose and reassemble web-pages to their tastes is an issue like inlining, framing, and linking: it's a matter of letting users innovate at the edge.

An Internet that allows people to create these features and people to choose to use them is infinitely more useful than one where copyright or trademark bullies can prevent us from doing so. More nostalgia: Link-it-all.
