Not really.
For example, if you read actual books and other sources about composition, these professionals are never this strict about the rule of thirds. In fact, some of them claim outright "there is no rule of thirds". And the others are only specifying it as a possibility, not as something you should follow all the time.
Even worse, these pictures they give as example dont even follow it. The bee in the first picture is simply in the center of the picture !!! And yet its the most interesting pictures of these examples. Teh.
Other stuff, like "framing your picture" - thats nowhere to be found in what I consumed about composition so far.
