Made a graph of the problem 
I’m following weekly launches of plugins and can see the quality has been going down lately… less big companies making plugins and a lot of the same use cases.
I think the success of ChatGPT plugins really depends on OpenAI implementing better quality assurance at this point.
There’s some really good use cases for plugins, but unless devs have a clear incentive to make them (should be easily monetizable, like iOS apps), and users have an easy way to find actual useful ones for their needs, it’ll remain a stagnating feature.
