Sometimes I wonder if they deliberately make it have such a low signal to noise ratio to make it harder for outsiders to efficiently get information.
But most of it is probably deliberately wanting to make it a form of entertainment and to be "personalities" and "content creators" in their own right. I suppose it's a fair tradeoff for being able to get what is ultimately some credible and predictive information now and then, but it does lend the risk of making PLA watching too colloquial, self-satisfied and too meme-heavy.
