I asked it a question that's pretty subjective and culturally specific, and I appreciate that I got a reasonable answer back. The question was "should I?" and the answer was "definitely, don't miss it" in three different ways. However, I found that the literal sources it quoted didn't have the same opinion it expressed to me so convincingly. I asked a clarifying question and it goes "okay so I read the material, and it actually says it's optional".
So why not read the material? I wonder if it could even embed the website in the results, giving the website the traffic and ad space. I wonder if a meta browser is a better product for these tools.
