Not anymore apparently, some topic such as Kahi Departure and Brickfair Virginia trend was on the front page for a week.
Another nitpick is some of the moc tend to be popular by the total likes rather than the amount of likes from the topic itself; for example, if there was a topic with 25 likes vs a topic with 3 likes and the comment stack up with 30likes together, then the topic with 3 likes will trend from another. The only exception I can debate with is a non-creative content.
