I think those are good ideas ;) It's important to display the topic's status (number of comments, popularity, solved question, etc.) as this community is growing bigger everyday and can be the most of resourceful forum in the future I hope.

Thanks for the suggestions Michael, we will be adding the number of answers onto the question pages shortly. At the moment we don't have any plans to close questions (and mark them resolved) I know some Q&A sites like yahoo answers have that system so it might be something for us to add in the future.
