Inkbunny is playing the long game here. Once all those cubs grow up . . .
bam. (But seriously, the site is remarkably easier to manage without the 13-17 crowd.)
Back on topic. Weasyl is doing a lot of things right. They have
some traffic, though only about 30-50% that of
Inkbunny or
SoFurry (
FA has ~7-8 times the reach of both).
Will it topple FA? Nah. But all it has to do is build its own community, keep them happy, and maintain feature parity with other sites. If and when FA does go down, it'll be a contender. They'll need to be ready for a rush of traffic, though, and the delays I've seen at peak times suggest they're not quite there yet.
