>> There's nothing in traditional media that works that way.
And that is exactly the point - it feels like we are finally waking up to what the web can really do that traditional media cannot. I'm sure in a few years having the content reflow will be something users expect of every website (not that it is something people do all the time - see the comment that guywithabike made).
I kinda agree, although my "search behavior" is slightly different from yours, so others may (will) be very different in their usage.
As well as a browser add-on (don't Google already have something similar to this?), I think it is more than likely that we'll see +1 buttons on web pages themselves (similar to Twitter tweet and Facebook like buttons), although obviously not every page will have this.
I'm not sure how anyone would be convinced that I find I can work faster with Firebug than other developer tools just by listing a bunch of features. shrug
> Why? What difference do you see between the browsers debugging-wise?
Feature-wise, very little. But as I said - I do find I can work faster with Firebug - I much prefer the the DOM inspector (one click node editing, css editing, the fact that it live updates the DOM as it is changed via any JS running on the page) and the console (DOM/JS object inspection and having XHR logging in the console itself and not on another tab). Plugins such as FireQuery also make a difference for my needs.
I can only speak for the Chrome/Safari WebInspector, and they're good, but I find myself going back to Firebug if I have to do any serious debugging - personally I find there to be a big step up in usability with Firebug meaning I can work faster.
It'll be interesting to see what happens to development tools when Firebug goes cross-browser.
