Is this sub a mindless echo chamber?

Pretty much the title. I guess I’ll have my answer if this gets deleted, but I can’t help but feel like no meaningful or interesting discussion about Ethereum takes place on this sub. It’s just headline after headline of “good” things happening for Ethereum holders, that just see this as an opportunity to make a quick buck, and they want validation from strangers that they’re right. But please tell me if I’m wrong, and if there’s a place where more meaningful, technical discussion of how the backend of ethereum is being developed, could someone point me there instead? Thanks.
