I saw many questions on MSE which are under bug tag and having many upvotes. Many times moderators and 10k+ users approve it as bug. And Many time people reports same bugs under different title and descriptions. Many sites provides bug reporting feature and it's status(familiar site facebook). So same questions can be deleted or closed immediately.
- Does MSE provides which bugs are approved and will be solved?
- Which bugs are solved until now?
