It's quiet here because when there was a flux of new members, some existing members went out of their way to make it clear some of the newbs weren't welcome. To make a few of the "originals" happy, this site sacrificed a large number of new members. Repeat that cycle a few times and when the originals slow their posting, the site content goes with them.
Both CF and TWF are pretty clear indicators that once people are turned-off to a site, they don't go back.
It doesn't help that trip is a nozzle, either.
