There are couple of suggested edits in the queue at the moment that add extra information to answers. The edits are for the following answers:
The information added by the edits seems correct and relevant (although I must admit I haven't verified it), and one of the suggestions comes from an extremely credible source so I would assume is definitely correct.
That said, I'm not sure if this would class as too 'Radical' an edit, as per one of the rejection reasons.
If I had to make a judgment on personal opinion, I'd probably just accept both of these (as they most likely add extra value to the site), but I'd like to know what the official stance is.
