Twitter already retrieves the content of pages that people link to in most cases, since they summarize the content in the form of a page preview (thumbnail, title, etc). I'd imagine that the reduction in knee-jerk retweeting, and improved understanding of the news by users when they read articles -- and perhaps answer a machine-generated question or two about them -- could lead to significant improvements in discussion quality. Hopefully Twitter would be able to develop metrics to measure that effect, and determine how it affects long-term user experience and value (bearing in mind that short-term engagement might drop a little). Perhaps it'd be worthwhile always allowing users to skip dialogs like this, since it's arguable they somewhat inhibit free speech (assuming tweeting a URL is deemed free speech). Whether the user was informed or not about the content they posted could be used as a quality signal about the tweet.
