When a duplicate or poor question get closed and the question at its whole own doesn't add any value to the community, I tend to immediately click
delete. Everytime it tells me that I can cast the vote after 2 days. Apart from the fact that it's annoying (why would you ever show an useless link in the UI?), it doesn't even remember the vote (actually, I discovered that today). The 10K tools also doesn't show anywhere a listing of closed questions which are really eligible for deleting. I would have to keep track of all those questions myself so that I can vote after 2 days (which I wouldn't).
I would suggest to either let that
delete link actually remember the vote or at least make this link disappear as long as the logged-in user couldn't cast the vote anyway and then add an overview of closed-questions-eligible-for-delete to the 10K tools.
