They didn't mention any way to indicate a questions worth. They said "status" as in, has someone proposed an answer that works. I think it would be nice because it might encourage to OP to come back and mark the answer that helped most, or post the answer they ended up useing. Its always frustrating to find a node with a similar question but that went unanswered (although you know the OP must have gotten something to work.)

As usual just my 2 cents
