I remember a post in Gamification meta which warned about the reasons why that site was likely going to close down, and now apparently it has.
I was expecting it, or at least its meta, to remain up for a little while, instead it already is in the "download the data dump" state.
Wouldn't it be useful for the SE sites as a whole, to have the meta of a dead site be active for a while (and the main site read-only), to discuss what went wrong?
Edit: thinking a bit more about it, I see no reason to close the metas at all. I understand that you want to close the main site, to prevent polluting google with links to a dead site, but meta would still be useful anyway, especially for future reference, and for discussing things relating the closed site.
