I think a very cool use of the “big blue area superimposed over preview” ™ would be alerting users that the exact same link appears elsewhere in the topic.

For example:

Say I am in a long topic … and in post #5 someone posted a link to `http://wow.awesome.com/cool`, later a different user comes and composes a reply containing `http://wow.awesome.com/cool`, odds are this is

1. A dupe post
2. Somehow strongly related to the post the submitted the original link

So we should simply display this in the blue area

> Bob already posted a link to `http://wow.awesome.com/cool` in post #5.
