I find it quite handy - it's a bit excessive on nearly every post, but it does add context when I don't recognise the news source, and it's useful to see whether I really need to do some more digging on the article rather than should look for other views on a story.
It's frustrating to see a comment or two on a post preview pane you're interested in though and boom, it's a bot rather than another user to engage with.
It would work really well as a plug in or tool, giving you inline information in the post itself.
I seem to recall Bushido Blade crudely implemented this in the late 90's, introducing rudimentary disablements on a Fallout-style limb system that would slow you down if you took a slash to the leg, or render your hand ineffective if you were struck there.
The slow march into middle age is making my memories fuzzy.
