Deleting old closed questions

Question

While we are in the process of doing some cleaning on this site, what should we do about old questions that are closed and not deleted?

If I think they should be deleted should I vote to delete and flag for moderator attention?

What is the best practice to get attention to these questions in a way that will assist mods and the new focus group?

Examples:

https://skeptics.stackexchange.com/questions/771/is-school-education-necessary-closed

https://skeptics.stackexchange.com/questions/5/what-exactly-is-the-burden-of-proof

https://skeptics.stackexchange.com/questions/7/why-did-the-randi-foundation-remove-the-1-million-dollars-prize

https://skeptics.stackexchange.com/questions/1009/what-are-multiple-myelomas-differential-diagnoses-closed

Answer 1

These questions have upvoted answers so they'd never automatically be deleted; this has to be handled manually.

(We have provisions for removing old 0 vote and negatively voted questions that have no significant activity over time, but that always precludes an actual answer.)

Thus I think the thing to do is what you are doing now, bring it up here.

The general philosophy of closing questions is that closure is a step on the road to eventual deletion; the main exception is duplicates where the other questions are needed as differently worded signposts to the eventual answer.

As for what should be eventually deleted, the criteria is simple:

Does the existence of this page make the internet better or worse?

Though I would also add

Does this existence of this question actively work against the charter of this Q&A site?

... as well.
