it seems like in every post there's a naysayer about something. you're complaining about an article that explains a difficult topic extensively and generously - in my day you had to pay really really good money for that. who cares if the title focuses one aspect of the explanation? sure it's a little deceptive but it's such a minor cost to you that you literally spent more time complaining than they deceived you out (click link with false notion, see length, close page). LPT: being critical in and of itself does not make you look smart.
