I dislike the idea of Google’s Toolbar “changing” anything on a web page.
While I dislike it I’m not going to call for ban or anything. Do what you want.
There only appears to be one person actively supporting it in my blog bubble. Cory. There are certainly a lot of good things that can be done with it. Like most things; however, this won’t be the case.
On the idea of the browser “changing” stuff: Imagine Google’s Toolbar swapping out BoingBoing’s ads with ads of their own. I’ve seen more than once the BB bloggers complain about their hosting costs, and what a pittance is left over. Hey, that’s cool. No beef. But, wait until someone appropriates your revenue for their own in form of a Toolbar virus, spyware, adware, doo-hickey.
Everyone has something they definitely won’t want changed (like mailto tages - no Google Toolbar doesn’t do this) and that’s really the point of objection for me.
Mind you, in a week I’ll have totally forgotten about this & will probably never think of it again since no one is really going to use this anyway in any meaningful numbers. Too much work.
