True.. nobody is perfect with such intricacies.
However, someone with lots of followers like Matt have to realize that every incorrect piece of information he shares is amplified and we can eventually see it on flyertalk.

One real life example is a certain travel blog that I won't specify.. He published a piece on JAL mileage program and credit card that was wrong.. Yes, it's a complex program but one of his false assumptions led to a rush of people posting in JL forum with this false idea in mind.
We can't control misinformation in this world, intentional or accidental, but people should take steps to prevent it if they can. In my opinion, that includes someone like Matt.
