I've seen this elsewhere and personally think it's a very useful feature. When questions have an answer marked as accepted, [solved] gets added onto the end of the page title. This then appears in search results on Google, etc with [solved] too.
I know it's not just me that adds the word "solved" onto the end of my searches to get quicker answers to problems. I always jump straight to these results first as it's pretty obvious there is more chance of getting my answer from one of these links. Just figured it might bring more people to superuser.com, etc. Only the title would need to change, not the links to questions themselves.
Is this something that has been discussed before or could possibly be implemented at some point? Or am I asking in completely the wrong place?
