Why should I buy in? just because you blamed w3schools as other guys did? you win by providing something better, at least show something instead of just talking

Why should I buy in? just because you blamed w3schools as other guys did? you win by providing something better, at least show something instead of just talking, do you have any of those? how about one chapter for CSS3 to give me a basic idea that why you will be better? It's never a good way to start by blaming someone else publicly while you have _nothing_ to offer on the table.
