I don't think that's close to true? However, this post and https://news.ycombinator.com/item?id=18079479, which is related, made it into the second-chance queue (described at https://news.ycombinator.com/item?id=11662380 and the links back from there). Not for any particular reason; they just looked like two good articles that the community might be interested in, which seems to be the case.

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.)

That's very natural, and we see this kind of clustering in many contexts on HN. You're right that a few posts in quick succession starts to feel like "all the time". Users come to HN to find unpredictable things, so the feeling of "haven't I just seen something about this" makes them cranky.

This is good stuff. Please don't feel unwelcome. Although the crowd here isn't the best suited for ML honestly (in terms of % distribution), please come join us on reddit.com/r/programming or boards.4chan.org/g
