I've been using Chrome for quite awhile, but today I got massively irritated with a page I was trying to read - and the built in "Reader" feature (yes, there are extensions for Chrome that do a somewhat similar job. No, they don't work nearly as well) was the only thing that made that possible. Why? Well, see how this page renders for you. For me, the Dubai add covers half the middle paragraph, and I can't see any way to dismiss the blasted thing. "Reader" at least centered it, letting me the see the page.
The real question is, how long will it be before Safari infuriates me over something, and I go crawling back to Chrome, or Firefox?
Update: A commenter pointed out that the Chrome 9 beta worked, and sure enough, it does. I'll stick with Safari until it irritates me though - which is certain to happen soon enough :)
