<p>I want to add another thought here, which hopefully isn't too far afield to be off topic (it depends on what "old" means). One thing I regularly do is scan the list of new badges every day to catch what have been considered the best questions &amp; answers of CV that I may have missed.  When I come across a <a href="https://stats.stackexchange.com/badges/40/tumbleweed">tumbleweed</a>, I also check those out. Now some questions don't get much attention because they don't have much merit, but once in a while I think a question does have merit.  In such a case, I often edit &amp; retag it explicitly for the sake of bumping it back to the top of the queue, and with tags / title / keywords etc., so that it may have the opportunity to get more attention.  Moreover, I gather this is the point of SE's having the tumbleweed badge.</p>
