There's generally less enthusiasm around the space, I can tell that. A few years ago, you would notice lots of topics about new stuff created and maintained, with fruitful discussion. Nowadays, it's just no longer like that. Bitcoin is seen as a digital gold, and that's pretty much it. Minimum cypherpunk spirit. This reality was extensively discussed in here:

Is there any rational explanation behind the fact that a Bitcoin forum -I repeat, a Bitcoin forum- is full of casino signatures?
Here's my take: This Bitcoin forum is full of people who want to get rich quick by gambling into shitcoins. If they can gamble on tokens made out of thin air, then they can definitely gamble on a casino.
However, my point is, is Bitcoin development so difficult? Is it a thing from the past? Nobody writes bitcoin-related software anymore? Why on earth isn't there any good bitcoin-related product advertised in the forum?
Bitcoin development is difficult and slow, but what relevant product have you got in mind that could be advertised? For all I know, barely any open-source Bitcoin software was advertised here in the past, in signatures.
