Cool feature, but it probably won't get much use. My mental image of the average IE user does not include configuring their browser, much less finding a good blacklist. This will probably be used mostly in corporate set ups, using a blacklist that the IT department maintains itself. I think the largest possible impact of this feature is that other browser vendors may start offering it, possibly with a pre-populated blacklist. On the other hand, I can't really see Chrome blocking Double Click or Google Analytics.
