I don't think it's completely a problem with search engines. Blogs like this are engaging some amount of SEO the may push a fairly low quality entry up in the results, and that is a never ending arms race between the search engine. The bloggers themselves initiate the issue, and I don't see how subject-specific engines could completely solve that. Why would they be able to distinguish this article from a well written entry on a SQL topic that is not just a restatement of fairly basic knowledge? Docs don't cover everything, there's space for articles like this that follow the same basic structure but with more useful information, a and once people can infer a little bit about the search engine's algorithm from how it shows results then we're back to the SEO arms race.
