Due to our teaching and research cycle, we do generally release a bunch of related things about once a quarter, around when new courses come out. So generally you won't see any fast.ai related news for a few months, then a few things might pop up in quick succession. That might make it feel like we're appearing on HN "every day".
(In fact, we have a major software release coming up next week - and then nothing planned until well in to 2019.)
