I think it is true with any distribution channel. When people figure out that it works, then everyone ends up bombarding that channel till it saturates.
Vibe coding is not helping either, I guess. Now it is even cheaper to create assets for the distribution channel.
I think same thing happened with product hunt.
Add in unemployment rates for devs... Everyone wants to make a side hustle into their job.
Product Hunt was launched with a non-straightforward approach intended not to appear on the surface as it works behind the curtain.
