Curation could be pretty simple: mere submission isn't enough, the submission has to have made it to the front page.
Given the anti-abuse safeguards already in place here (since getting a submission to the front page is an attractive goal already), I wouldn't expect that any attempts to get a link included in that collection would succeed.
How about making a tag, section or filter that's a "best of"? Maybe even a option to add in old posts to your feed? say at the bottom of the first page is a "best of" submission.
