Although I like the idea, I personally prefer Pulse.me. It has pictures and resized articles according to their significance.

I'm a big fan of "significance", "buzz", and "personalization" in theory, but I find it easier to skim some text myself.
I find that I can skim more easily with a few images that provide additional visual cues other than those of textual information. Pictures require a different visual focus, and might allow me to focus on the "bigger picture" (e.g. whether it is coming from WSJ), or "smaller picture" (i.e. more specific examples).
Additionally, I like that you can mix the sources together, with not too much of anything; instead emphasising a more holistic view.
I'd argue title words are much better at showcasing an articles potential value than a stock image of a carrot.
