In the olden days, desktop apps shipped with credits screens with the names of individual contributors (sometimes in the splash screen, sometimes in the About panel, sometimes hidden in Easter eggs).
Then they went away! I don't know if it was IP concerns, the fact that it gave headhunters a hitlist of people to poach, or just got unwieldy.
Sometimes SaaS apps have a friendly "Team" page on their site with headshots and bio blurbs, which is the closest I think I see nowadays.
Are any of you shipping credits screens in your desktop, mobile, or SaaS apps? If so, why and how? If not, why not? Should it be revived?
