The user guide tells you how to use Codeigniter and how it acts, it doesn't tell you how to solve every problem.
Also that thread is not discussing an error or really a problem. They are talking about how they think code igniter should act. The documentation is very clear, and it does exactly what it says it will do. Return false if no results are gathered.
If you think the user guide is pointless you dont have to read it, but you'll find that most people will direct you to it when you ask a question that is simple answered by looking at the user guide.
If you want I can setup and entire codeigniter installation that works on my system and then send it to you with detailed instruction on how to set it up.
Other wise, every time you run into a bug I would like you to supply the full source of the files. In this case, the blog controller and blog_view.
