Got a maybe a silly idea for some time in the future.
When user posts a new topic, it will go to a section called "New Topics" not the index page). So, users can vote on it. If, lets say topic gets "5" upvotes, it will than gets to be displayed in a main page under category person created a topic under. If not, it gets burried without showing up. - Sort of, let users moderate whats gets displayed on site according to their needs.
