Hey ED how about when people leave AB ( or dont log in for a month or so) you ask them why? Then publish the results - I would LOVE to see these results.
People come and go all the time .I fail to see what business is it of yours ,the Editors or anyone elses why they don't log on or leave .It's not compulsory .
It's a website that is enjoyable/interesting when you have some time to spare - but is forgotten when life gets busy. Some people take it too seriously.
