I've definitely noticed a dropoff in my interest in Show HN. I used to look forward to seeing Show HNs on the front page, and even posted one that was moderately successful, but now it seems like very few posts ever make it.

Meanwhile, going to Show HN directly feels very cumbersome to me. I can't explain it, maybe due to all the techy nomenclature mashed into one page, it's just very off-putting.

On the other hand, Ask HN has been my favorite source of HN content lately by far.
