Referencing a blog is fine. But when you're on a forum discussing ideas just forwarding a blog link is bad taste. Summarize the key arguments. Do some work.

It's like if someone is arguing free markets and I just provide a link to a WSJ editorial. It's rude, requires no work on the sender and imposes work on the receiver to read and synthesize and respond to the argument. I see this occasionally where someone will just have an LLM generate a response (which it will happily do for any topic taking any position) and just passing it off.
