We don’t, and it would be a nice feature to have (though a low priority). However, through a combination of the following, going without doesn’t present a huge issue:
- Others can flag the question to bring it to our attention, and (almost) anyone can link it through our walls if it appears we don’t notice.
- We’re still users of the site, and will notice continued activity on closed threads: especially ones we personally made decisions for.
- Irrespective, we keep track of closed threads if they’re the type we’ll eventually remove. Good chance we’ll come across any updates.
- If we’ve left a comment on the question beforehand, we’ll be notified anyway.
