Hi David,
On the contrary, I wonder if this (and offering the page organized by age) wouldn't be a good place to spot packages being adopted for a too long time, so people may wish to take action. In this regard we could also add (and organize by) last activity.
perhaps I misunderstood the Debian meaning of adoption ... I thought adoption is close to family life. If I adopted a child five years ago, it is (at least formal) part for the family for five years. To me being adopted meant being worked on (including new updates) in the debian context. I am okay with any other solution indicating or avoiding outdated information. It is highly appreciated that you already discuss it with Justin. Regards Martin
