Over in the AskUbuntu meta, I found it worrying that many search engines direct people to duplicates because their titles are more searchable. Often (or so I guess from looking at the viewcounts), people visiting a duplicate page do not make to the leap to following the Possible duplicate link to the original, answered question.

Could duplicates just embed the actual question in the closed link to avoid visitor confusion? Like so:

In the above page, Upgrade Ubuntu 10.04 to 11.04 would remain the <title> and <h1>, while How to Upgrade from a very old release to the latest would be an <h2> (or perhaps just a <p>) visually styled like the title. The answers to the original question would also be listed below.

I think this would make SE's duplicate system more user friendly, and better optimized for search indexing.
