Not all but majority of the gay porn sites that have regular updates on a weekly or daily basis usually include the date each scene was released. Big Daddy has been doing it since it started. This is currently the front page of Big Daddy which showed the date for each scenes.
Yesterday, when I visited Big Daddy, the front page was different. It seems they are testing a new design that did not show the dates. When a porn site starts removing the dates usually indicates fewer updates or worst, no updates.
Or, maybe this type of design attracts more membership?
