It would certainly be helpful to have release dates, especially for those of us with huge porn collections who need spreadsheets to catalogue what they've got. Seeing a scene was released '3 years ago' is so vague it's of no help at all, especially if it's an actress like (for example) Lara Sins, who seems to release a new anal scene every other week. But ideally the third-party scenes would need to match up with whenever they first released a scene.
