An auto-unclose process that examined web logs for direct hits from google might be nice too. And closed question that gets N hits from google probably deserves to be reopened with a special "google wants an answer" tag.
I usually (always) search google for my problem de jour. And frequently (enough so I remember) the first stackoverflow result is my exact question... but closed. Probably happens once or twice a month, and usually on something "thorny" (i.e. no clear cut answer... so "primarily opinion based" answers are fine... I can compare the top voted answers and decide for myself).
Sometimes I find a two year old post on HN that I want to comment on, but it's "closed" - the reply button is gone. HN should implement that when N hits from Google occur, it bumps it back to the front page and makes it able to be discussed again.
More seriously though, Stack Exchanges platform isn't designed to handle opinion polls and endless discussions. You might want to consider asking the question on a site geared to opinions and discussions such as quora or reddit.
Also, are answers to closed questions stored? If not, and there is a new often used unclose workflow, it would be nice to let users still store their answer, to become visible when it becomes unclosed. This would help with the timing issue and would also give mods a way to see 'oh wait, looking at this answer it is actually too interesting to deserve these close votes'.
