No I don't see anything like this they were very active at the forum , as long as the bitcoin is in the market it is obvious that bitcointalker will be also here, and she per the bitcoin condition in the market I don't think bitcoin will disepare over a night.
Thanks for clarifying the gender of crypto and this forum.
Now let us discuss what OP asked. Here is what I fee about the current state of the forum.
1) Merit system has increased the quality of posts in some sections. There are some bad effects as well but they should fade with time.
2) Signature campaigns have reduced (may be because of less demand for crypto).
3) Moderation is currently quicker than what it was when I joined.
