but it is not the case with all the wordpress blogs. There are plenty of wordpress blogs that aren't spamming the web and they are high quality and valuable blogs.
As Matt says in the video, BUT look past the idea that it is "Wordpress only". What he is telling you applies to
ABSOLUTELY ANY WEBSITE whether it is Wordpress, Joomla, Drupal, vBulletin, Invision, SMF, Pligg, Moodle, a 'wiki', blog, forum, hand coded in notepad or
WHATEVER. It starts off with WordPress because he is talking about the
mechanics of building a site that is 'crawlable' and accessible. Beyond that, the advice on content, copywriting, word research, and providing what
USERS WANT is applicable across the whole spectrum of website management.
Your short sighted view of "It's about WordPress" is precisely why so many "experts" are complete clowns at Search Marketing, simply because they FAIL to see the
bigger picture and concentrate solely on the minutiae of the mechanical aspect of "search engine friendly" websites.
