quite a few questions on this meta branch are technically "unanswered". some are about general information of a durable nature, but some have clearly outlived their shelf life.
is it desirable to close those questions that are no longer of interest except to a possible archaeologist? i'm thinking, for example, of the moderator pro tem announcement. many of these questions (like the present one) are tagged "discussion".
i'm not sure how closure would be accomplished with zero answers, but i think it's worth thinking about.
