Finding and interviewing ex-editors

This is great news! I'd like to work with him on the survey. I think this has the potential to be our most useful source of data. But we want to get a good mix of questions, without overwhelming people to the point that they don't feel like answering.

We also need a different survey for different stages of leaving. Users we survey on the first, second or third anniversary of their last edit are likely to have acquired some perspective on their experience; whilst users who just posted "retired" on their users page more often than not will be back in a day or two.

Do you think we'd ask them different questions? Or would we just get different answers? If the latter, then we can probably just ask a few questions about timing up front... and then see if there are any trends based on that.
